This post was originally published over at jooq.org as part of a special series focusing on all things Java 8, including how take advantage of lambda expressions, extension methods, and other great stuff. You’ll find the source code on GitHub.
Apart from Lambdas and extension methods, the JDK has also been enhanced with a lot of new library code, e.g. the Streams API and much more. This means that we can critically review our stacks and – to the great joy of Doctor Deprecator – throw out all the garbage that we no longer need.
Here are a couple of them, just to name a few:
There are lots of libraries that try to emulate LINQ (i.e. the LINQ-to-Collections part). We’ve already made our point before, because we now have the awesome Java 8 Streams API. 5 years from today, no Java developer will be missing LINQ any longer, and we’ll all be Streams-masters with Oracle Certified Streams Developer certifications hanging up our walls.
