Java KeyListener: KeyTyped Backspace, Esc as input

Question

Inside the KeyTyped method, how do I tell if Backspace or Esc is being pressed?

Answer 1

Assuming you have attached the KeyListener properly and have implemented the methods required for that KeyListener, to detect specific key-presses simply add the following code:

public void keyReleased(KeyEvent ke) 
{
    if(ke.getKeyCode() == KeyEvent.VK_BACK_SPACE)
    {  
        //code to execute if backspace is pressed
    }

    if(ke.getKeyCode() == KeyEvent.VK_ESCAPE)
    {
        //code to execute if escape is pressed
    }
}

The KeyEvent class javadocs can be found at the following link: KeyEvent javadocs.
There you can find a list of all of the Java virtual keycodes used to detect keyboard input when implementing Java KeyListeners and KeyEvents. More information about KeyListeners can be found here: How to Write a Key Listener. To use the keyTyped method as asked, see gangqinlaohu's answer.

When arg0.getKeyChar() is cast to an int: (int)arg0.getKeyChar(), The backspace key comes up with the value 8, and the Esc key comes up with the value 27.
