Free JAVA course, [Y] or [N]?

Sup /prog/.
I am being given the opportunity to take a course in JAVA for free from my house.
I know a little bit of VB.
Should I take it?
What does /prog/ think of JAVA? Could I use it to widen my horizons and understand more of programming?

But I cuold use it to write JAJAscript, would I not?
