  Just make the 200 line boiler code setup to make some

  system.stuff.thingy.log.println(“hello world”);

  Then it’s not compatible with the installed vm.

    Then it’s not compatible with the installed vm.

    This almost never happens, unless you do very niche things or have unrealistic expectations from your file system.

    Niche things include using obsolete cyphers for net communication or running java code on the ibm mainframe, not something you do day to day.

    Java has changed a lot since Java 8. Here’s a 3-line HelloWorld.java compatible with Java 21+:

    void main() {
        System.out.println("Hello, World!");
    }

  It makes me cry when modded minecraft uses 100% of my CPU and eats up 20gb of ram. (This is only a little bit java’s fault)

    1. Java should not be used for game engine design. Stop-the-world events and poor shaders support do not help.

    2. JVM eats as much memory as you give it, so try playing with -Xmx param

      Java has been used by programmers of mobile games just fine, for ages. The trick is the same that one would need with any other environment: knowing what objects you’ll need to allocate, and not allocate more than that.

      Oh yeah I know all about that, I’m talking about what it actually uses within the JVM 😅 It’s a messy monster of a game once modded, and there’s really nothing you can do about it other than some slight optimizations here and there.

    Is that why there’s like 27 languages that are based on the same jvm?

      I feel weirdly drawn to learning kotlin.

        You should, it’s fun to use and runs on pretty much every platform.
