Pawno into Java

I've been watching tutorials, reading books, reading java documentation to get to know it better before I start out my college, so I can get that background info/knowledge.

But I've been wondering, if maybe I am to create a game
basically on pawno we do stuff like To acccess player attributes/variables in an easier way

So I was wondering, how can I do such thing in java?

EDITED: Pawno to pawn - pisses a lot off
