I'm new to JAVA. What should I know?

[cybershark]

I'm at college and we are learning JAVA. Right now we are at if/else and switch commands . Where should I focuse more? I mean whats the main thing I need to know so I can understand JAVA better?

Also JAVA right now looks so easy but I'm afraid I might forget those things when harder things come up.

What should I do to be a better JAVA programmer?

The list might be shorter if it contained little used features that could be skipped until later.
I'll start with my short list:
Applets are not used
For GUI chose Swing or JavaFX
regular expressions could wait

Why alot of programmers say that GUI is not important?
I think it is very important, because once programmer tries to make program work outside eclipse- ( btw how to do it ) it is a must.
Because without GUI there is no way to create games or software.

I didn't realize a lot of programmers say that.

That statement makes no sense to me. Many programs work outside of Eclipse without a gui. And you don't need a gui to create
software. It may help make it easier, but it is not required. And some key software development tools don't depend on gui's
such as compilers and source code control systems.
