The Robot.keyPress method takes in an int key code -- not an actual character code.

From the documentation regarding keycode:

keycode - Key to press (e.g. KeyEvent.VK_A)

Therefore, entering the following will not work:

Robot r = new Robot();
r.keyPress('a');            // Won't work -- it will press an "1"

To work correctly, one would have to use the constants from KeyEvent:

Robot r = new Robot();
r.keyPress(KeyEvent.VK_A);  // This works -- it will press an "a"

Also, if one wants to use the KeyEvents returned from a KeyListener's events such as keyPressed and keyReleased, the KeyEvent object has a getKeyCode method which will return the keycode of the event.
