I generated it with this plain bruteforce:

import java.awt.event.KeyEvent;                                                               
import java.lang.reflect.Field;                                                               
import java.lang.reflect.Modifier;                                                            
import java.util.*;                                                                           
                                                                                              
public class Test {                                                                           
    public static void main(String[] a) {                                                     
        for(int i = 0; i < 1000000; ++i) {                                                    
            String text = java.awt.event.KeyEvent.getKeyText(i);                              
            if(!text.contains("Unknown keyCode: ")) {                                         
                System.out.println("" + i + " -- " + text);                                   
            }                                                                                 
        }                                                                                     
                                                                                              
    }                                                                                         
}

I have excluded the "unknown" codes.

e is the KeyEvent.

if you want to see the e value, then you can try this

System.out.println(e.getKeyChar());

Creating KeyEvent :

KeyEvent e = new KeyEvent(Component source, int id, long when, int modifiers, int keyCode, char keyChar, int keyLocation);

Example (dunno if this is the right way, but it produce the right output):

Button a = new Button("click");
    KeyEvent e;
    e = new KeyEvent(a, 1, 20, 1, 10, 'a');
    System.out.println(""+e.getKeyChar());
    System.out.println(""+e.getKeyCode());

Here is the all type of KeyEvent parameters

java.​awt.​event.​KeyEvent
@Deprecated public KeyEvent(Component source, int id, long when, int modifiers, int keyCode)
Deprecated. as of JDK1.1

===

java.​awt.​event.​KeyEvent
public KeyEvent(Component source, int id, long when, int modifiers, int keyCode, char keyChar)
Constructs a KeyEvent object.
Note that passing in an invalid id results in unspecified behavior. This method throws an IllegalArgumentException if source is null.
Parameters:
source - the Component that originated the event id - an integer identifying the type of event when - a long integer that specifies the time the event occurred modifiers - the modifier keys down during event (shift, ctrl, alt, meta) Either extended _DOWN_MASK or old _MASK modifiers should be used, but both models should not be mixed in one event. Use of the extended modifiers is preferred. keyCode - the integer code for an actual key, or VK_UNDEFINED (for a key-typed event) keyChar - the Unicode character generated by this event, or CHAR_UNDEFINED (for key-pressed and key-released events which do not map to a valid Unicode character) 
Throws:
IllegalArgumentException - if id is KEY_TYPED and keyChar is CHAR_UNDEFINED; or if id is KEY_TYPED and keyCode is not VK_UNDEFINED IllegalArgumentException - if source is null
