//Create an array of keycode data
static int keyInput[] = {
KeyEvent.VK_H,
KeyEvent.VK_E,
KeyEvent.VK_L,
KeyEvent.VK_L,
KeyEvent.VK_O
};//end keyInput array

public static void main(String[] args)
throws AWTException,IOException{

Runtime.getRuntime().exec("notepad");
Robot robot = new Robot();
robot.keyPress(KeyEvent.VK_SHIFT);

for (int cnt2 = 0;cnt2 < keyInput.length; cnt2++){

if(cnt2 > 0){
robot.keyRelease(KeyEvent.VK_SHIFT);
}//end if

robot.keyPress(keyInput[cnt2]);
//Insert a one-half second delay between
// characters.

robot.delay(500);
}//end for loop
}//main
