Thanks! Everything looks very familiar. Is that's all to know about Java (the language)?

Certainly not. To understand what's possible with Java (the language), you should look over the extensive API available for use as well. This is what you get for free with Java.

I added the language because I am not interested in the libraries. I'm interested in the syntax and semantics.

Pretty much. If there's anything missing, you can usually assume C/C++ syntax. (reminder - no pointer distinctions in Java though)
