Import java.awt.AWTException;
Import the java.awt. Robot;
Import java.awt.event.KeyEvent;
public class RobotExp {
public static void main (String [] args) {
the try {
Robot Robot Robot new new = ();
// definition of delay of five seconds so that you open the notepad ha
@ Robot began to write
robot.delay (5000);
robot.keyPress (KeyEvent.VK_H);
robot.keyPress (KeyEvent.VK_I);
robot.keyPress (KeyEvent.VK_SPACE);
robot.keyPress (KeyEvent.VK_C);
robot.keyPress ( KeyEvent.VK_A);
robot.keyPress (KeyEvent.VK_O);
robot.keyPress(KeyEvent.VK_E);
robot.keyPress(KeyEvent.VK_R);
} catch (AWTException e) {
e.printStackTrace();
}
}
}
