Why not use keyReleased[^]

Another option would be to use both keyPressed and keyReleased and if you have already jumped after the key has been pressed, you wouldn't jump again. In pseudo code, something like

@Override
    public void keyPressed(KeyEvent e) {
        if(e.getKeyCode() == KeyEvent.VK_SPACE && jumpOk) {
            jump();
            jumpOk=false;
        }
    }
....
<pre>@Override
    public void keyReleased(KeyEvent e) {
       jumpOk=true;
    }

Just remember to initialize the jumpOk variable to true when you start this part of the program
