Answer 1

You don't say where you got it from, etc., but Eclipse gives you hints based on what it can determine from your code and what code is it's libraries.

IIRC: Where you see the yellow exclamation double clicking that will give you a list based on what it thinks you meant (I find that it is right about 90% of the time) or (AFM) press F1 when the caret is on that line.

Answer 2

First google result for KeyGenerator.getInstance("AES")
