I want to write a Snake game in Java. How can I continuously monitor input and if user pressed W set variable Char lastDirection = 'w'; //hence, Direction.UP?

I know about the Scanner method: Scanner scan= new Scanner(System.in);... But then user would have to hit enter each time he presses the button. Document Listener (Swing) seems better, but then i would have a long string of user input saved somewhere that I don't need. What is the right method for listening to keyboard and remembering the last character?

Answer to the "possible duplicate" question is irrelevant, because I was looking for a Swing compatible method, not a Console API. My question was probably marked as a "possible duplicate" using grep utility triggered by a keyword Scanner.

KeyAdapterworks well with Swing components for this task. http://zetcode.com/tutorials/javagamestutorial/snake/
