Although this works, it's a bit annoying that I have to change the batch-files everytime I want to compile or run another class...
I'm a bit hesitant though about downloading programming software without knowing what it actually can do...
I don't want to use a big "suite-like" program because the fun for me is not so much in making a big fancy program but in writing the code itself!
Therefore the question: is there another way/a program to do this?
What I could really use is just a code-editor with a compile and a run button and a frame to display compiling- (and yes, I'm a newbie, runtime-) errors (and without fancy extra's, options, etc.)
You are probably better off at a beginner's stage using the command line directly. Use Notepad++ as a text editor; it is really good for editing program text.
You never double-click a class file to run it.
