I may work with java soon, so I was reading about Spring and it was yet again a dive into insane amount of verbose over engineering that I ran away from years ago. It's true that post 8 Java becomes palatable. And someone on reddit just showed me this piece of stats: https://www.jetbrains.com/lp/devecosystem-2019/java/ 83% on java 8, java 11 nicely going up I pity those forced to work with old techniques

I write quite a lot of Java, and I have to admit I never “got” Spring. I’d much rather have explicit boilerplate code (preferably in library form as much as possible) than complex, invisible magic. The latter is “easy”, but the former is “simple”. In most cases, “simple” is more important.

> Once I show them Java 11 with var keyword, lambda's and streams they start appreciating how modern the language has become. I wrote a lot of Java, but it was a long time ago. Could you share a bit of code representative of the modern Java 11 style you mentioned (var keyword, lambdas, streams, etc.)?

Not the guy that you were asking but Trivial example: public static void assertIsSuperset(Collection superSet, Collection actualSet) { final List missing; missing = actualSet.stream().filter(x -> !superSet.contains(x)).collect(Collectors.toList()); if (missing.size() != 0) { /* Imagine some more verbose exception creation here, which is why we caught it in a list*/ } } The lambda is in the creation of 'missing': filt…

  public static void assertIsSuperset(Collection superSet, Collection actualSet) {
    var missing = actualSet.stream().filter(x -> !superSet.contains(x)).collect(Collectors.toList());
    if (missing.size() != 0) {
     /* Imagine some more verbose exception creation here, which is why we caught it in a list*/
    }
  }

In my experience most people don't like Java due to experiences they had before Java 8. This means they were used to the bloat, config as XML style world which made Java a pain to write and slow to run. Once I show them Java 11 with var keyword, lambda's and streams they start appreciating how modern the language has become. Then you throw in frameworks like javalin or sparkjava and suddenly they are not as hostile a…
