Java AWT 中的机器人类

Java AWT 包中的 Robot 类用于生成本地系统输入事件，用于测试自动化、自运行演示和其他需要控制鼠标和键盘的应用程序。 Robot 的主要目的是促进Java平台实现的自动化测试。简单来说，该类提供对鼠标和键盘设备的控制。

下面是 Robot 类如何控制键盘并在空白记事本文档中键入内容的示例。如本文所述，记事本是使用 Process 和 Runtime 调用的。

Java

// Java program to demonstrate working of Robot
// class. This program is for Windows. It opens
// notepad and types a message.
import java.awt.AWTException;
import java.awt.Robot;
import java.awt.event.KeyEvent;
import java.io.*;
 
public class robo
{
    public static void main(String[] args) throws IOException,
                           AWTException, InterruptedException
    {
        String command = "notepad.exe";
        Runtime run = Runtime.getRuntime();
        run.exec(command);
        try {
            Thread.sleep(2000);
        }
        catch (InterruptedException e)
        {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
 
        // Create an instance of Robot class
        Robot robot = new Robot();
 
        // Press keys using robot. A gap of
        // of 500 milli seconds is added after
        // every key press
        robot.keyPress(KeyEvent.VK_H);
        Thread.sleep(500);
        robot.keyPress(KeyEvent.VK_E);
        Thread.sleep(500);
        robot.keyPress(KeyEvent.VK_L);
        Thread.sleep(500);
        robot.keyPress(KeyEvent.VK_L);
        Thread.sleep(500);
        robot.keyPress(KeyEvent.VK_O);
        Thread.sleep(500);

        Thread.sleep(500);
        robot.keyPress(KeyEvent.VK_S);
        Thread.sleep(500);
        robot.keyPress(KeyEvent.VK_F);
        Thread.sleep(500);
        robot.keyPress(KeyEvent.VK_O);
        Thread.sleep(500);
        robot.keyPress(KeyEvent.VK_R);
        Thread.sleep(500);
        robot.keyPress(KeyEvent.VK_G);
        Thread.sleep(500);
        robot.keyPress(KeyEvent.VK_E);
        Thread.sleep(500);
        robot.keyPress(KeyEvent.VK_E);
        Thread.sleep(500);
        robot.keyPress(KeyEvent.VK_K);
        Thread.sleep(500);
        robot.keyPress(KeyEvent.VK_S);
    }
}

输出：

The code opens a blank Notepad file and types 
"hello from geeksforgeeks" onto it with a delay
of 500 ms before typing out each character.
