Java => shorten commands for the robot

Hey, using this piece of code:

try {

      Robot robot = new Robot();

      robot.keyPress(KeyEvent.VK_H);
      robot.keyRelease(KeyEvent.VK_H);
      robot.keyPress(KeyEvent.VK_A);
      robot.keyRelease(KeyEvent.VK_A);
      robot.keyPress(KeyEvent.VK_L);
      robot.keyRelease(KeyEvent.VK_L);
      robot.keyPress(KeyEvent.VK_L);
      robot.keyRelease(KeyEvent.VK_L);
      robot.keyPress(KeyEvent.VK_O);
      robot.keyRelease(KeyEvent.VK_O);

 } catch (AWTException e) {
      e.printStackTrace();
 }

I get this result:

hallo

But is there a way to shorten this process? for example something like:

try {

       Robot robot = new Robot();

       String  word = "hallo";

       // something like:
       robot.keyPress(KeyEvent.word);

   } catch (AWTException e) {
       e.printStackTrace();
   }

I know this example does not work, but I could not find documentation about it.

Do you have any ideas? greetings and thanks

If you are using Java 7, you can use the method KeyEvent.getExtendedKeyCodeForCharto get the key code from char:

   import java.awt.event.KeyEvent; 

   [...]

   public static void type(Robot robot, String word) {
        for (int i = 0; i < word.length(); i++) {
            int keyCode = KeyEvent.getExtendedKeyCodeForChar(word.charAt(i));
            robot.keyPress(keyCode);
            robot.keyRelease(keyCode);
        }
    }

   [...]

   Robot robot = new Robot();
   type(robot, "hallo");

Make such a method. Just use methods that take a character.

public void press(String s, Robot r)
{
    for (char ch : s.toCharArray())
    {
        if (Character.isUpperCase(ch))
            r.keyPress(KeyEvent.VK_SHIFT);

        r.keyPress(Character.toUpperCase(ch));
        r.keyRelease(Character.toUpperCase(ch));
    }
}

Or you can use this to get KeyCode.

KeyStroke.getKeyStroke(ch, 0).getKeyCode();

Or also

KeyEvent.getExtendedKeyCodeForChar(ch);

Hope this helps.
