Java terminology is the first thing you should look up when trying to learn.

Write down every term and definition on note cards and read the word first then the definition last. After you recognize the word so good you don't need the definition to understand what the word means then set it aside and read the other words you don't remember. Once you remember them all make more. Java has tons of different words and symbols that do different things. Once you master them all, you need to understand how to piece them together like a puzzle. You would be a pro at Java then. That is the level I need to reach.
