I couldn't figure out which factory to use to instantiate the object I need, so I checked the java doc. It was merely a list of the 1,000 classes in the package with no comments. I asked online for help and was told that question was answered on the mailing list like three years ago.

In Spring you have to include terms like "AutowireCapableServiceProvider" in your class name as well.

I made an online scientific calculator using BigDecimal back in 1998, using Java 1.0. It actually got cited in a bunch of math papers.

what does bigdecimal mean?

@@velo1337 BigDecimal is a datatype that you find all over the place in most Java code bases. It is often used instead of floating point types since these are not accurate for things like monetary and scientific calculations. It can be quite verbose and confusing to use though. Ideally, there would be a simpler type right in the core language.

​@@velo1337 It's a type for calculations when you need more precision. A simple sample could be an interest calculation of a Loan.

Hello fellow fintech!

funny enough, most banks and fintech companies who use Java dont even look in the general direction of BigDecimal - instead they keep using float and double for everything and they even split complex mathematical problems into several smaller operations - all of which also use float and double and are several hundred times slower than BigDecimal _(and its actually somewhat hard to be slower than BigDecimal - that takes effort)_ ... and : this approach automatically summons precision problems and rounding errors but "management doesnt care", instead they'll continue to enjoy their sexual fetish for deadlines, lines of code and the likes.

@@ololh4xx Financial software without precison ? WTF ?!

@@Hexanitrobenzene @ololh4xx As someone who worked for a mortgage servicing company and who is dating someone who works at one of the big banks, precision problems in finance is a given. Pennies are constantly either disappearing or spontaneously created from nothing because of a lack of precision when working with percentages that give >2 decimal point results.

​@ololh4xx more languages need to fully support IEEE754. Decimal floating points are part of the standard yet only binary floats are ever used or given first class support

Why not just doubles? So you have a nullable type?

​@@dovi Doubles will ruin your day if you're doing anything that requires precision like with money. You always want to store money as a whole amount. In our case, we use a tenth of a penny.

hahahaha so true. The thing behind a VM that runs bytecode is nice. The creator of the JVM said, that webassembly was exactly what he had in mind. :) But didn't turn out to be. Guess now the future is Rust + Webassembly (if you need a VM) and if not.. just Rust. (The name webassembly is also bad, its not for web only... )

Had to make a java interface for a COBOL program in development, which meant I was working close with the one who did COBOL full time, and ended up reading through the code myself. I didn't hate COBOL, sure it is a bit dated but definitely a valid option. The COBOL dev who joined the company around the same time as me and learned the language on the job ended up getting hired by a much better paying company after a year of using COBOL.

I hate Java but dynamic reflection is actually useful and even necessary in some cases. For example if you're writing a Minecraft mod (in some framework like Forge for instance) you may need to change a thing at runtime or get some internal thing that's private. If you're only shipping the mod, which you usually are if you're working with a modloader, then your mod needs to use reflection.

At my internship I had to compare objects using RecursiveComparisonAssert. In one class a field wasn't named as expected by the naming convention so that field failed my test. I changed it's name and oh well this solved 1 problem and caused 10 others lol

@@pyroandi6797 I had so many issues with dependencies autogenerating code in reference to field names, Lombok and Mapstruct to be precise. Holy damn that stuff is hard to debug.

That is what encapsulation is for, to be worked around with bytecode engineering and reflection.

@@jamess.2491 I thought that’s a feature, not a bug. So you can play your favourite game in between xD

Java is not C++, compile times in java are barely an inconvenience.

@@agcouper not in my experience and judging by other people, I am not alone in that. Then again, my main experience with Java is old and big enterprise peojects. In any case, I was just making lighthearted jokes, you can write your code in brainfuck for all I care. Besides my biggest problems with Java is not the compile time or the jvm, rather some of it’s ideologies and also the over use of “patterns” for everything and the oversegmentation of everything into thousands of classes, where a few hundreds would do the trick. But I do acknowledge that the last (and my biggest) problems I described are a fault of the community and developers, not a fault of the language per say

When people talk about Java, I actually ear Java Spring Boot, otherwise it's unmaintenable

spring boot is good?

Fast to launch, but not fast to launch, If you know what I mean.

@@oliverweiler8113 yeah, apparently the micronaut framework looks like spring but solves the slow startup times.

@@test4274 No. No, it is not. It is interesting that AOP is actually possible with pure Java, and the defaults make it easy to write simple apps if you follow the tutorials closely, but as soon as you try something exotic, like having two controllers, you'll end up working around Spring Boot with more effort than if you had never used it in the first place.

Nowadays anything can run anywhere. It's a technology called vm containers. Very magical, very recent.

Actually everything runs on top of a Linux nowadays. No need for multiplattform

Java developer here, and yeah, multiplatform is not a main benefit anymore for java, basically most languages have it now even without docker. Still java is considered an all rounder in many aspects, you get a lot of stuff right, maybe except for syntax sugar and productivity.

@@fsismael still good when you want to develop on windows and deploy to Linux and be guaranteed that everything will work 100%

I prefer using C/C++ , when in need of performance. If prefer using Python, whenever management asks me to do something by yesterday and time is of the essence. Which happens like 90% of the time! My preferred decisions would just be to purge Manager1.bf , to replace it with a totally rewritten Manager2.bf containing an incredibly optimized task scheduler ...

No, Rust will not replace Python. Rust is supposed to replace C, and it might, or maybe not. Python has replaced Fortran. If anything is set up to replace python, it's Julia, but I don't expect that any time soon. Java has replaced COBOL. It was supposed to replace C++, but it failed spectacularly in that regard: C++ has replaced C++. C# was supposed to replace Java, but instead C# is the new PL/I. Kotlin is replacing Java.

the day that those languages are going to be unused we will have AI that write it for us and we wll be unemployed, don't worry about using any language for now, we are probabily the last generation of human coders

@@sharkpyro93 AI is just a trap term for stupid people, the only thing i believe in is machine learning, it's impressive if you read some books on it, but it's not magic, it's like the other guy said AI it's not artificial(it's made by humans) nor intelligent, it's most relies on human intelligence to recognize statistically some patterns to reproduce, and of course the blazing computing power, if there will any day that AI is a real thing like you see in Prometheus movie for example, that would be in hundreds years from now, probably in a thousand years if humanity is till on this universe, maybe we will blow out ourselves before that, we still don't know mostly 90 percent at least how the brain works, how it get's it's energy given how infinitely complex it is, it's not just sugar and carbohydrates, still didn't explore 99.99999 percent of the universe, that is the things i believe in, we don't know shit .. like one philosopher said, the time it's take you to read the Odyssey 2000 years from now is exactly the same as now, even will all the technology we have there is infinite amount of things to explore and know
