I know Eclipse may be dated, but this is the main reason why I like to use it: it compiles a file when I save it. Java program then starts instantly - because it is already compiled - regardless of it's size... But I think you can also configure IntelliJ IDEA to compile on save and even use Eclipse compiler so you can compile and start programs with compile errors...
