Typing a single key generates two KeyEvents. These events must be handled by implementing the KeyListener interface. It has three methods corresponding to the three actions that can occur on a key:
-
public void keyPressed (KeyEvent e)
-
this is called for an action key, such as arrow keys, home, etc.
-
public void keyTyped (KeyEvent e)
-
this is called for other keys, such as text characters
-
public void keyReleased (KeyEvent e)
-
this is called when any key is released

Typically, one uses methods to find the name of the key pressed or typed:
-
String s = e.getKeyText (e.getKeyCode());
