To start off please be aware that I'm real newbie here and I would really appreciate anyones help.
I only started to learn Java about month ago going by a book called Head First Java second edition. I have some previous experience with Visual Basic but that's about it. So this probably gives you an idea what kind of newbi we are dealing here.
Anyhow, I'm struggling to use the debugger feature - namely whatever I do I cannot get the debug panel up where you can also see all variables etc. I did as I've seen on some youtube videos by adding break line and then running the debug. It runs, it even displays some information on Messages Make window (it even states its using javac 1.8.0_102 to compile java sources, so I guess that has been set up correct). It even notes some intentional errors that i have left in etc.... but all this in Messages Make window. If I look from View->Tool windows I can see from there that Debug (Alt + 5) is always greyed out. I tried the free standard version and also the Ultimate Trial version. No difference. I'm running Win 8.1. So I think I'm doing something really wrong.
I would be extremely thankful if someone can help me. I've spent hours on googling and trying different things to resolve this. Right now learning Java is super important to me and I really like this software as it looks awesome.
