Robot類用於為測試自動化、自運行演示程序和其他需要控制鼠標和鍵盤的應用程序生成本機系統輸入事件。Robot 的主要目的是便於 Java 平台實現自動測試。
使用該類生成輸入事件與將事件發送到 AWT 事件隊列或 AWT 組件的區別在於：事件是在平台的本機輸入隊列中生成的。例如，Robot.mouseMove 將實際移動鼠標光標，而不是只生成鼠標移動事件。
我們可以利用這個類寫出好多有意思的東西，下面我將詳細的這個類的用法。
Robot這個類中的方法並不是很多，常用的有以下幾個：
void delay (int ms) 睡眠指定的時間（類似於線程中sleep）
void keyPress（int keycode） 按下指定的鍵
void keyRelease（int keycode） 釋放指定的鍵
void mouseMove（int x，int y） 將鼠標移動到給定的屏幕坐標上
void mousePress（int buttons） 按下一個或多個鼠標按鍵
void mouseRelease（int buttons） 釋放一個活多個鼠標按鍵
void mouseWheel（int wheelAmt） 滾動鼠標滑輪
下面看一個自動實現HelloWorld的例子：
package autoHelloWorld;
import java.awt.Robot;
import java.awt.event.KeyEvent;
public class Main {
private static Robot robot;
public static void main(String[] args) {
try {
robot = new Robot();//創建Robot對象
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
//這裡是按下和釋放alt鍵，這個鍵的功能是調用菜單
robot.keyPress(KeyEvent.VK_ALT);
robot.keyRelease(KeyEvent.VK_ALT);
robot.delay(500);//延遲500ms
//這裡是按下和釋放回車鍵，用於確定是file選項
robot.keyPress(KeyEvent.VK_ENTER);
robot.keyRelease(KeyEvent.VK_ENTER);
robot.delay(500);
//選擇New
robot.keyPress(KeyEvent.VK_ENTER);
robot.keyRelease(KeyEvent.VK_ENTER);
robot.delay(500);
//選擇Java Project
robot.keyPress(KeyEvent.VK_ENTER);
robot.keyRelease(KeyEvent.VK_ENTER);
robot.delay(500);
//輸入字母a,即工程名
robot.keyPress(KeyEvent.VK_A);
robot.keyRelease(KeyEvent.VK_A);
robot.delay(500);
//回車確定創建工程
robot.keyPress(KeyEvent.VK_ENTER);
robot.keyRelease(KeyEvent.VK_ENTER);
robot.delay(500);
//將鼠標抵用到剛剛建立的工程上面，這個坐標是作者在自己的電腦上實驗獲得的，在不同的電腦上可能不一樣，可以用
//Point point = MouseInfo.getPointerInfo().getLocation();
//System.out.println(point);來打印當前鼠標的坐標，從而找到對的位置
robot.mouseMove(43, 136);
//按下和釋放鼠標左鍵，選定工程
robot.mousePress(KeyEvent.BUTTON1_MASK);
robot.mouseRelease(KeyEvent.BUTTON1_MASK);
//alt鍵選擇菜單並調出newClass的選項
