34. KeyListener interface

• The KeyListener interface receives actions that user initiates from the keyboard

• Declares three methods:

  
      keyPressed()  // character typed -- no calls from function keys
      
      keyTyped()    // function keys and keys not generating any characters
      
      keyReleased() // used in most cases, including function keys
  
  

• The keyReleased() does not take action while user holds down key

• The keyTyped() is platform independent -- preferred way of handling the keyboard.

• The keyPressed() and keyReleased() are platform/locale dependent.
