How do I create key press event using Robot class?

In this example we use the java.awt.Robot class to generate a key press event. We can call the keyPress(int keyCode) method to produce this event.

package org.kodejava.awt;

import java.awt.AWTException;
import java.awt.Robot;
import java.awt.event.KeyEvent;

public class CreatingKeyboardEvent {
    public static void main(String[] args) {
        try {
            Robot robot = new Robot();

            // Create a three seconds delay.
            robot.delay(3000);

            // Generating key press event for writing the QWERTY letters
            robot.keyPress(KeyEvent.VK_Q);
            robot.keyPress(KeyEvent.VK_W);
            robot.keyPress(KeyEvent.VK_E);
            robot.keyPress(KeyEvent.VK_R);
            robot.keyPress(KeyEvent.VK_T);
            robot.keyPress(KeyEvent.VK_Y);
        } catch (AWTException e) {
            e.printStackTrace();
        }
    }
}
