Java.awt.Robot class controls the mouse and keyboard

The Java.awt.Robot class is used to control the mouse and keyboard. Once you get this kind of control, you can do any type of operation with the mouse and keyboard through your Java code. This class is typically used for automated testing. The following code sample shows you how the robot class handles keyboard events. If you run this code and open Notepad, you will see Hi caoer in Notepad. Try it quickly.

import java.awt.AWTException;
import java.awt.Robot;
import java.awt.event.KeyEvent;
public class RobotExp {
public static void main(String[] args) {
try {
Robot robot = new Robot();
//定义5秒的延迟以便你打开notepad
// Robot 开始写
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();
}
}
}

Users have perfected the above code:
