Docs are online everywhere but try here:

http://java.sun.com/j2se/1.5.0/docs/index.html

But the best solution is to download the zip file and put it on your
computer, (near the bottom of the page):

http://java.sun.com/javase/downloads/index.jsp

I know some people can remember all of the syntax but I have to have the
docs to refer to.

lol, thanks. Just for the reference, the code I was using came
straight from an example in a textbook. Just out of curiousity, where
did you get that documentation, so I can add that to my knowledge base.

Thanks

I am trying to implement a keylistener to react to when the enter key
is pressed.

Below is the code for keyTyped method:

    public void keyTyped(KeyEvent key){
        int keyCode = key.getKeyCode();
        System.out.println(keyCode);
        if (keyCode == KeyEvent.VK_ENTER) {
            Toolkit.getDefaultToolkit().beep();
            System.out.println("ENTER pressed");
            queryConnection();
        }
    }

However, the 'if' statement is never executed. When I look at the
output in the command prompt, the keyCode is 0 regardless of what key
was pressed. Any ideas?

RTFM:

"For key pressed and key released events, the getKeyCode method returns
the event's keyCode. For key typed events, the getKeyCode method always
returns VK_UNDEFINED."
