That's actually a problem when people discuss about languages. They don't understand that there is a difference between Startups and big Corps. The later want applications they can easily maintain for the next 10-20 years. So they don't use the new and shiny stuff, they use the stuff that works and has proven itself.

I still remember 3 years ago watching Stefan on KZfaq Fast forward , I gave myself a better chance by teaching myself coding while having a full time job as cabin cleaner working around 60 hours a week am average and still manage to code on the side. Good new- I have been working as full stack engineer for 5 months now and it is my first job. Tech stack: Java. Spring , Postgres’s, React, aws s3 and some internal tools 🧰. Yes it is a corporate amd it is remote but still need to dress while meeting with managers amd stuffs. This video is really accurate Stefan knows exactly what he is talking about. Thanks my friend

React frontend + Java backend skills will get you a job guaranteed. Python is good for learning stuff, for DSA, and online assessments. However Java gets you in the industry

Stefan, LONG time fan. I secured my first job as a Server-Side Java Engineer. I also very much enjoy how explicit the language is and enjoy the workflow. Coding is a big slow I agree, but it's such a fun language to code in. I appreciate you mentioning Kotlin and I need to begin my learning towards that. I have a solid foundation in Java, but I would like to begin focusing on Kotlin now. It's amazing how accurate this video is. I'm a good interpersonal "professional" communicator and so is EVERYBODY else on my team.

Once any small company starts to grow. They always switch to Java on Server Side. And keep JS based Front End.

7:17 I don't understand, a missing semicolon would cause a compile error. Does your friend not work with an IDE that catches it before he commits?

This is absolutely true! Recently got word for a job at a well established vehicle company that is building their software in Java and most of the job is basically back-end work communicating with the servers, etc., but the pay is so good... The job is a "hybrid" model (office and some WFH), but people are pushing for more WFH days for the devs.

The most important thing in a corporate environment is code readability. Far more so than how long it takes to write code. A senior developer will typically spend 80% of his/her time to read and understand existing code that needs changes.

Very good and accurate analysis of Java development. I work at a big bank and everything is shifting to java/spring boot microservices (of course COBOL and mainframe will still be there for the next 50 years). Working in this setting means that you will have to deal with people and do lots of compromises and prioritizations of different tasks, but for me that is a positive. I'm not writing code every hour of the week, which can be nice sometimes. Lots of unforeseen issues show up all the time. You never know how the week will turn out. I just want to say this to whoever is reading: If you like programming, but also like to deal with people and use your social skills, then working for a big corporation is a good place. Corporations are setup like the army; if you put in work and give good input, it will not go unnoticed. The pay is also very good. And yes, we run java 19 + all the new shiny tech. Not all corps are slow to change, but it really depends on the tech culture in the corp.

I agree with your assertion regarding the type of work you will be doing with Java, you have pretty much described the first five years of my programming career.

Hey Stefan, i thought this might interest you. Three months ago I finally got my first job as a fullstack web developer at a really tiny company (8 people in total). I applied for a frontend position, but it turned out that i have to do everything because the other five developers are busy mostly working on a big project for a bank, and i take care of the smaller projects for other clients. I absolutely love that, learned an incredible amount of stuff in a short time doing that. I absolutely get now that it is crucial to get a job asap btw, never could have learned all this by myself. Here comes the interesting part. Turns out, we use vuejs, spring boot and a postgresql database for pretty much everything (im working on one project with spring boot + thymeleaf rn though). The configuration and overall structure is almost the same between projects, so when a new customer comes along, you can usually just copy a template project and tweak it a little bit. I asked my bosses why they dont use something like nodejs, and they told me they had done that amongst other things, but always ended up coming back to spring boot. I have to admit i didnt completely get the technical reason, it had to do with scalability, maintainability and modularity i believe. A reason i could think of is that you can use it for absolutely everything, even though it might be overkill in some cases. Also all three of the companys founders had worked on enterprise level projects before, so maybe they just use this stack because it is what they like and know best. Anyways, just wanted to let everyone know that not every job in java is at enterprise level. Keep in mind though that i applied to a front end position, didnt have a clue about java and the spring framework before i started working there. They told me i got the job because they were under the impression that i could adapt to a new language/framework/technology quickly, and that was one of the things they were looking for. In fact i showed them a python project i was working on in the interview, it didnt even have anything to do with web development. Never would have thought of learning spring boot to find a job in a small company, which is what i always wanted. Another thing to mention is that i live in germany, so maybe the job market is different here.

I recently went through a Java Web development training program. It isn’t that slow to write basic Rest APIs w/ Spring Boot. But once you try to add Spring Security/Oauth it definitely is challenging. For beginners, the most difficult part is learning how to use Maven’s build tool to add dependencies. Also, Spring itself is used for way more than just web development. I think it’s flexible for many use cases and Maven/Gradle is the most intimidating part.

I agree with most of the points, having said that, Spring boot has advanced a lot. A lot of manual configuration has been eliminated, also the performance with reactive java with project reactor is unmatched. Not to mention the proven longevity has compelled organizations to use java. Now with kubernetes, docker and new ci/cd pipelines, deployment is not an issue.

Personally, I like Java for prototyping in industry (aeronautics). I work in a R&D department in a big company, the portability is great, the verbosity is nice for complex algorithms, easy to learn, has good perf, etc.. We are able to run it on Raspberry, drones etc. For me it's a little step before passing the algos in C++ for MVP. If I need something more technical I run Matlab.

Thank you so much for the breakdown. This has given me a lot to think about when it comes to career decisions I'm struggling with right now

Well articulated. Good advice for some new in the workforce.

I have yet to meet a single experienced jobless Java developer. So conclusion is that => Learn Java

Strict typing, in conjunction with simplicity, is more important than both write speed and runtime speed. This is why the overwhelming majority of jobs posted are in Java and C# in pretty much every city. Companies tend to want to eliminate a whole class of errors that comes with loosely typed languages like Python, which is why Python is mostly used in academia rather than industry. Even on the frontend, companies are moving toward Typescript. Languages like Rust and C++ usually don’t make the cut due to their complexity. They have the strict typing part but C++ in particular defeats the whole purpose by introducing a new category of bugs (pointer-related). A company needs to be in a position where speed is a serious priority for them to commit to those languages.

I will tell you reality. Good Java coders who know their shit around Spring, hibernate, JPA, spring security, spring boot etc. are in super high demand. Corporates are going out of their way to hire good Java engineers and paying extra. Plus if you are already working in a project for sometime, there is a job security angle which many people prefer. The reason is that Java is very hard and scope is humongous when you consider all the frameworks around it. There is no substitute for Java when you are talking about building real time data engineering

I've been doing web development for 20+ years and still find your videos insightful.

Sir I really appreciate you for making this video. Because i was confused which Language to chiose because many KZfaq videos are suggesting so many different languages and libraries with frameworks. No you're making some of my decisions lighter. Thank you so much sir keep it coming 🙏❤️ love from Papua New Guinea 🇵🇬

Hi Uncle Stef, just found your page and let me tell you i am hooked on this channel and your other one. I am 24 and started my journey couple months ago with wanting to get into this industry and only been focusing on Java, so I’ve been teaching myself before i start a bootcamp and i am hungry for it. To be completely honest i want this life style, to be able to provide for my family, to be able to do things i love, have TIME over all and the list goes on. I am and want to be confident this is going to be my future but i know i much to learn. I have looked into your website (looks great) but not the code i want to learn. Do you have advice for people getting into this field of work and lifestyle or anything that comes to you? Thank you

I went to Java because I knew I was going to work with big companies. I work to a Brazilian digital bank that went international. We work mostly with Java 11+ ans Golang. What I like the most here is that we have little dress code (any kind of long 👖 and any kind of t-shirt without logos and drawings) and they are really good with the remote work model. We also have a really simples deploy pipeline, a lot of DevOps implemented, we run all in AWS. May be I'm in a really new niche for Java, with modern deploy pipeline and modern server side architecture. It was nice to here your opinion about it, because I may be working in a company that is the exception for Java. I'll ponder about learning Golang

This is my basically what the team I'm being on boarded for is doing lol. Thanks for sharing . honest and accurate.

I did my 3rd semester project in java, and then my final year project for the completion of BSCS. And i love java since then, as you mentioned here i too love the explicitness of Java, plus the fact that it has excellent IDE support (which makes the developers' life a lot easier). Also it gives you the power to develop desktop (windows, mac, linux), mobile, and web apps. But seeing it go off the development landscape is heartbreaking for me. The fact that desktop apps aren't in demand anymore (large organizations which develop desktop apps usually develop their apps in c++ for obvious reasons), google have almost phased out Java in favor of Kotlin (not bcz of the benefits of Kotlin but bcz Oracle tried to sue Google over the use of java in Android), and of course the availability of Node.js have shaken the web development world, and java wasn't even close to PHP or ASP. NET in backed development tools.

Thanks! Very informative!

I have a good experience in both express/js and spring/java. The biggest difference between the two is that js lets people do really stupid things that leads to some crazy bugs. For that reason, e prefer spring/java.

Hello, thanks for this video I had recently left my previous job as a Java springboot developer working on huge enterprise apps And your video has tempted me to reconsider what types of jobs I'll be getting into next Since as you said, Java Development is just much much slower than python or javascript development

Really nice video, good an rather unique perspective

Stef man you're a legend, really appreciate your content as it gives me tons of motivation. Best wishes from Lahore, Pakistan

I am a backend developer working on microservices with spring boot. Agree with almost all the stuff except for the part where you mentioned that it takes a lot of time to configure spring applications especially with XML files. This used to be the case until Spring boot took over and its been a while. It doesn't take much time to develop in Java as long as your task is well defined to begin with. Also as a developer, semicolon is embedded in my subconscious.

Wonderful video on this topic. Thanks 👍

Hello Stefan! That's awesome video for someone who loves writing code in Java. I will slightly disagree from your Spring boot point of view. The older versions of Spring MVC like 7-8 years Old, yes they required lots of configuration files but now a days, the Spring boot made life really easier. Its all annotation based and handles most and most of the boiler plate code in itself and by its AOP paradigm it actually lets the developer focus only on business code taking away almost all of the cross cutting concerns. You can write a complete MVP in just few hours if not minutes with a valid RestAPIs, FrontEnd or anything you like. Moreover to compliment spring boot with other front end tech like React/Angular, there comes other Scaffolding frameworks/tools like JHipster, you can write a complete MVP Crud app with proper front end and back end layer in just couple of minutes and then build upon that as MVP gets approved.

If you're looking for a job, generally speaking you will want to learn a language that has loads of jobs available for it. I made the mistake of learning Elixir and building a full product with it and still cant find a job because im not a senior engineer and there just arent many junior jobs in the elixir space. Java might be hella verbose but if youre looking for work, I'd say its a good place to go for your first job/language.

Java being used mostly for web and android development? I don't think so. I don't think anyone is using Java for web development these days. Most web development is being done with the fancy Javascript frameworks. For android, they're probably mostly using Kotlin too. Now where is Java being used? It's being used heavily for backend development. Can't think of any language threatening its position for a long time. Maybe Golang in the long run. It's true though that it's mostly being used in large companies but it's not true that it's only being used for legacy code. If a company uses Java in its backend, a new feature requiring a new microservice will likely be written in Java. Also, write time speed is greatly increased with Spring Boot with its convention over configuration approach and increased even more if you use libs as Lombok and new versions of Java containing features such as vars and records. Also, a LinkedIn search for Java + Worldwide, Javascript + Worldwide or Python + Worldwide returns similar number of postings, so there's great need for all of them and Java isn't going anywhere. Also, remote work is here to stay, regardless of the size of the company. Last but not least, use the "right" tool for the right job. If your plan is to do frontend development, dive into javascript frameworks and you'll be fine. If you want to work with backend development, learn Java, Go or Node. If data science/ML is the plan, then go for Python. Mobile? Then Kotlin, Swift or Flutter. Low level? Then C/C++ or Rust. The frustration comes when you try to use the "wrong" tool for the right job, for example, having a backend written in Python, etc.

Thanks for this video. I am a civil engineer who got sun microsystems certification way back in 2000 or so but did not use it until lately for android apps. But Iwas using AutoLisp/Vlisp for automatic design calculation and drafting using their Lambda functions which gives the AI capability. However I find that java since 2014 has added that option which gives me the same AI capability for generating my drawings on any CAD system via DXF code. I wonder how many have realized this huge boost for java in engineering?.

Very good advise. I had java jobs, my new c++ and a bit python job, is much more fun, the resons being what you expose. Very nice advise.

does that means that whatever new release that comes out from java of spring boot framework, it might be not common that companies will be upgrading to new version, as you said mostly legacy code that a java developer typically do in the job

Agree 100%. Another negative aspect of the Java world is that interviews are focused on syntax oddities and heavy leetcode recipes and boring stuff like that.

Typical helpful video by Stef, full of nuggets of information that you won't find elsewhere. My C++ instructor at BU Corp Edu Center [late Dr. James Devlin] used to hate Java; he would say "you don't get the colaaan colaaan with Java", referring to " :: " the scope resolution operator. Question Stef: What kind of language would one use if one wanted to write a script to manipulate the play-time of youtube. For example, while going to bed I put on a long video or playlist, but I want youtube to stop playing the video after 45 min let's say, without shutting down the computer. I know I can schedule the shutdown of the computer in my Linux from the command line. Python, best option? Or would one use a shell script?

You must have a great job. Congratulations! They are rare. I started programming in Java when it was a new language. I've been developing Java for over 30 years now. I've encountered all kinds of employers since then. I'm still developing new Java Apps. I'm also maintaining legacy code. This is the life of a software developer. You speak in generalizations which apply no matter whether it's a new langauge, an old language. It doesn't matter if your young or if your old. It doesn't matter who you work for. The soft skills you speak about are important everywhere. Javascript, and Python are older technologies than Java. There are many legacy apps that are written in Java. Many companies are still using Java. Java, like most languages, will grow and stay relevant. You do say some thigs that are true. A company will use whatever technology is important to their business. Consider where and what you want to do and work towards that goal.

this is exactly what i imagined when i picture a senior java programmer

It is definitely useful advice. However development speed has very little to do with how much boilerplate you need to write. Kotlin mixes very nicely with java, it could be a natural successor in the enterprise. I guess you can hate the enterprise for many reasons, but startups are probably not any better.

So what you're saying is Golang would be amazing as it has the simplicity, epic write time speed, easily maintained, fast to compile and is fast!

Awesome as always👍

Im currently starting a new Java project at a mid sized company using Quarkus. It's like a lighter spring boot. Having lots of fun working on it so far.

Stef is spot on as usual. I’m a self taught I broke my way into the industry and I cut my teeth on Java. Currently got hired on a big old legacy project in telecom. It is what it is. Pays the bills. I’d like to be on a nimbler newer stack.

I'm very surprised you didn't mention the strongly typed aspect of Java when comparing it to other dynamic languages like JavaScript and Python. Development speed is one thing (and debatable given the maturity of Java frameworks like Springboot) but debugging time, and refactoring time are also important. Yes, it's true Java jobs tend to be in large companies, not just banks but Faangs companies as well.

Hey Stefan, what is your opinion on high level languages that build on top of the JVM like Clojure, and what about GraalVM Native Image and AOT for Java?

The autoindustry is using a lot of java in the cars, so sort of embedded, also some IOT solutions and frameworks.

As an experienced coder what is your idea about data science and job opportunities?

Amazon / AWS is like 95% Java + Lombok + Guice/Spring/dagger even on micro services. With Lombok there is no more boiler plate or verboseness and with Guice/Dagger/SpringBoot there is no more config / xml Honestly no difference in what the apps look like compared to typescript now

As an ex BA for a bank, I can confirm, I had to be there with the devs during deployments and it’s hell. I had to work without more than Sunday afternoon off for two months Terrible environment and everyone was sooo against ágile

Is it the same case with C#/.Net?

Isn't it true that now with the help of AI like gpt, write time of any language would be considerably faster? If so, the run time speed should be considered more.

I work for a large company and maintain legacy Java code based built using Spring Framework. I have worked in many languages but maintaining legacy code base is extremely frustrating and not rewarding. I have now removed Java from my resume and will no longer work in Java. Think before you learn Java and apply to jobs that make you maintain legacy codebase. Sometimes companies hide the true facts about the job so be careful. It’s not worth the money.

Is there a video about all the common programming languages and the pros and cons of each? If not, would be nice to see a nice summary for all, for a new guy looking for direction.

Javascript and Python maybe look like they are easier to write, but because they are easier and freely-typed, they could lead to catastrophic results on the long run, especially if they are common among younger developers, and businesses owners who only care about fast results.

I am learning Full Stack Java development and i am blown how Java is super badss. One thing we were clear initially that WTF it is, but now as we are about to get close to Springboot after the hibernate now it all makes sense now. One thing I learnt that the further we go, the easier it gets to code as the basiscs (Core Java) had been done for that advance Java.

I’m learning Java and I enjoy it I was learning python but I stay with Java cause my understanding is as some one with no experience probably would be easy to get a job as a Java developer then python as for most jobs in python I would need a degree, also seems am new I like the idea of working for a large company, I could be mistaken and if so could someone share some light

So in this case would C# be better to learn for backend development?

hello, can you talk about golang? im a dev usingg java for 1 year now, and i want to know if i should spend my time specializing in java or learn golang and try to convert to that

Even though the majority of the Jobs in Java are corporate ones, that's not the whole thing. Several tech first companies runs on Java, such as Netflix and Spotify, and the whole behavior thing leans more on the startup side than the corporate side. I work at one of this tech first companies for 3 years now, and I can not complain. Scale, doesn't matter where, necessitates more stable and reliable languages and stack. Consolidate frameworks and companies such RedHat, Confluent and Oracle supporting it.

yeah comments are right im working as backend java using mainly spring-boot and you can write an API with CRUD operations in 10 minutes. spring-boot is now agile enough as compared with older spring

I agree with you about most java jobs being in the larger corporations and supporting legacy apps, but it sounds like you haven't used Java and Spring for the last 15 years or so. Nobody uses xml configs anymore. The time it takes to write the code is not that massive anymore either. Newer frameworks encapsulate tons of boiler plate code. You just need to use annotations.

Hi stefan..... please explain why you feel write time >run time..........but we generally write code once and run it many times.... please explain more.....i am confused

Thanks Stefan, I wish I watched this video a year ago, when I started studying Java based on a recommendation of a programmer that had just landed a job in that language... I lost touch with her, and I am already somewhat advanced in Java to switch languages, and as you said, I started suspecting some months ago that it was going to be hard to land a job as a Java developer, especially without a degree... I have though about not completely abandon Java but starting to learn Kotlin and maybe the HTML, CSS and JavaScript trilogy to see if its easier to land a job. Would you recommend something for that purpose for those who are already well into Java without a degree? Thanks! 😄😄

With Spring Boot, configuration is minimal and, even if I'm just starting to look into it, it's awesome. As a matter of fact, the. Net framework seems to be copying this approach. For backend development, Java is great!

is it wise to use it for a startup? is it still used in startups?

Great video, but I have to disagree with some stuff: First I think you may not be up to date regarding Spring-Boot or Spring in general. No one configures anything with XML these days, it's "just" Java Config + Spring Boot heavily uses the convention-over-configuration-approach, so if you are not doing something funky you don't really have to configure that much, since you only configure the CHANGES to a default installation. Java may be very verbose and you type a lot more than with other languages. But imo you overestimate the impact on your productivity. The hard part is usually figuring something out, the actual typing is like 5% of my job AT MOST. Also: what's the alternatives? Writing the backend in C# or Express is not that much faster than Spring-Boot (if at all) and you loose the big of advantage of Java: it's a very mature language with mature frameworks for just about anything you could possibly need.

3:11 using intelJIdea everything in short-cut like psvm ,do setter-getter many much more shorcut that no issue!

I love Java. Been using it since version 6. Used to do heavy business stuff. Write Minecraft mods in it these days.

I just got a 3 months Java internship in a big organization. I would like to learn flutter to try do develop mobile apps after internship

Stefan, so which language would you reccomend for more smaller and more dynamic projects, python, PHP, JS, and would you like to record video about that sort of working?

Chasing missing semi-colons is not really a big deal if your IDE is good. Spring, as well, is mostly annotation-driven these days and less XML-driven. Spring has found its place in the microservices world, but a microservice architecture is not necessarily the best solution for every product. Services that are considered monolithic tend to be made worse by Spring.

developed in Java for over 20 years on the server and JavaScript on the client but now everything seems to be going JavaScript with Node and the MERN stack.

I'm a Java developer and you got it perfectly

Though I had worked with PHP last 7 years, the longer I work as dev, the more I prefer strictly typed languages... Especially when project is not fresh startup. Or so small that only you are working with it.

One big question. Where do you see something like redhat jboss java based middlewear? I do unfortunately like the redhat based offers. Yes, I know, do not want flac after IBM and centos. But I do think for corporate redhat can stand out. Is their OS easy to use... Nope. Definitely not beginner friendly but it does force people to think about security. Generally Uncle Steph. What is your view on Java as a middleware like jbos?

You're right. Interpersonal communication and networking across teams is incredibly important in enterprise size environments. I'm interested in your opinion if the same sentiment applies to the direction of C#/.NET. My experience has been that C# is also used in smaller to medium sized teams for both legacy (.NET Framework) and greenfield (.NET Core) development. Would you say that .NET is a safe choice balancing the maturity and stability that larger companies value along with a new resurgence of "hotness" with the latest updates over the past few years? I enjoy writing C# but the company I'm currently at uses Java - Luckily I'm focusing on front end, but don't want to let my full stack chops slip.

My compromise is pushing our team to use Kotlin for server side JVM. So much less boilerplate and quite a bit easier and quicker to write. Our requirement is being compatible with company Java based frameworks, so Kotlin first perfectly 😀

Maybe I worked for corporations too long, but interpersonal skills have always been more important than coding in my software career.

The original C++ language did not have a direct compiler. You would write your C++ program, and, then run it through a utility, I don't know what to call it, that would turn it into pure C source code, and, then compile the C source into a functioning program. Anything like that for Java? Something that is not wordy?

When it comes to writing vs run time, is that still as relevant since now there are tools like copilot and IDEs that can auto-complete?

I code for many years and used multiple languages through the years. Most of the current higher level languages are not as different in terms of produtivity as many insist, specially if people use the right toolkit. I mainly program in Java because it's powerful in many ways (it can be very simple but also allows much more complex and structured code if needed). For most of the things, such as Web applications, APIs, I use Vert.X, that is extremely fast and basically as simple to implement as with any other modern language. I won't use anything else just because I can have a few less lines of code or some function or syntax that allows me to do a lot in a line, even if it's not readable code. People are alwas trying to reinvent the wheel in programming, but only in rare ocasions the wheel was indeed reinvented or substancially improved.

How would you compare Java to C#?

My mentor often says, to learn concepts not language's syntax. And Java has solid concepts you can learn and implement even in frontend (angular)

Maybe you are not up-to-date. Spring Boot is very lightweight, bare minimum boiler plate code and config. No more xml, simple yaml config file or annotation driven. Very performant and the standard "de facto" for every modern Java development, suitable even for startups. Obviously legacy code is a different story but this apply to every language. Still a very good overview from you.

being an amateur - i got write time speed down a fair bit by getting vba to (re)write vba code i know all you real coders are going to say yuck, but it works

Hello. Has Swing/JavaFX become a niche ? Thanks for your answers

Everything you said I lived it in past two decade, now we are in decade 20 ... but you are right, very well explained.... green field projects are still there, and I think the cost of migrating some projects to use newer technologies will become too expensive and risky.... as a consequence maintaining code base in their language versión and framework will remain there ... everything must be translate into a budget and cost/benefit relationship ... and yes again SpringBoot at this point seems like everything they said they won't be...I used to configure my application and dependencies, etc, etc ... SpringBoot initializer comes a bunch of things already give what of repositories, etc, etc, etc ... is for sure and without any doubt shipping software using SpringBoot the market delivery velocity is accelerated but then.. where did all cool tasks that we engineers use to checkout and configure and implement, etc, etc, etc .... if it is not fun... why do it anyway? ... But I understand 100% what you are talking about .... thank you for express it and communicated now I know I'm not alone neither crazy. Will check your channel might get a subscription action there... saludos,. =)

I have been working with Java / Spring boot at multiple large banks for about 4 years, working with legacy code bases and building brand new from scratch applications. I gotta say it is a love hate relationship. (Mostly hate, but at least it’s not Ruby) But what can I say, that pay though

I just finished a 32 week fullstack merit america java program, I love the language just worried about the market.

my concl so java, is huge enterprises commonly. and js , php, py, is small and low/mid paid but can you tell me what other language called huge enterprise other then java cause java too hard please

How is the job market for C sharp compared to Java's?

I think you should have a few more java people to give you an idea. That friend that uses java in his company doesn't seem like they use any devops practice and seems like a monolith. I agree it's more for bigger companies.

everything he said about java is absolutely true it's been a year since I started my first job and it's 100% wfh thankfully but most of the time it's just boring and don't ignite your passion I'm hoping to switch over to c++ and maybe work on cool stuff like 5G but there's a lot to learn

This channel is gold 🪙🪙🪙💪🤘❤️

while im still learing java how i can use my java knowledge what should I do to improve it Im little lost :

I've worked for big and small organizations (including a few startups) outside of Silicon Valley for over 20 years and most of that time I was writing Java. I've written Java at startups. Lots of startups don't use Java but many do. You're spot on that if you do Java development you're also doing backend web application development. I think Java is a great choice for startups because it has a large community with tons of well-written libraries and well-established patterns. I've dabbled in Kotlin and if you know Java it's easy to transition to Kotlin. It's basically Java 2.0. I've written Javascript and Python and they are completely different beasts but I wouldn't say they're "nimbler" by any stretch.
