Design Patterns Revisited in Modern Java by Venkat Subramaniam

Design Patterns are common ways to solve problems that developers have discovered over time. They often fill the gaps between the language capabilities and the design goals. When languages mature, sometimes patterns become natural features of languages and blend in to the natural way of writing code instead of a special effort. Java has evolved significantly over the years. In this session we will revisit some common design problems and see how patterns are realized to solve those problems with the modern capabilities in Java.

"code should reflect empathy" - the best take ever!

I had a interview test about 2018. Their solution was classic strategy mine was a 1 line lambda...Patterns were often countering limitations in the old java. Unfortunately, devs often still write this old style java as they do not know about latest function support.

this so true

The individual is encouraged to adopt a practice of sincere empathy towards both their RAM and the GC. Such consideration has the potential to significantly improve the system's performance and overall efficiency. The notion of embracing this approach is highly appreciated.

Oh, the statement above is not solely focused on the GC, rather, it encompasses the entire virtual machine of this particular computer programming language.

The purpose of decorator pattern is to add new behavior to existing object dynamically, but refactored solution with Function(s) look more like chain of responsibility/strategy, not decorator.

The funny thing is that, he had to prepare all of these specifically for the presentation, he probably never used any of this in his projects LMAO, because most devs would not understand it and the maintainability of the application goes down. Can confirm i've been developing production grade software for 7 years and never used any of these lambda shenanigans. You will mostly only use lambdas in streams and api methods that take lambdas as arguments, you will pretty much never be abstracting away stuff by creating your own predicates and functions.

Well if you don't, you should, as long as developers understand it, maintenability actually goes up.

Congrats, you just realized that talks like this have examples. Everything he said has been an irl problem before ... That's why design partners are a thing. Most design patterns won't even exist if java has a proper type system. Idk why java devs hate change. My OOP prof that taught java docked marks for using records that have been out since java 14 or so. Y'all need to get with the times lmao
