void keyPress(int keycode)按下给定的键
void keyRelease(int keycode)释放给定的键
void mouseMove(int x, int y)将鼠标指针移动到给定屏幕坐标
void mousePress(int buttons)按下一个或多个鼠标按钮
void mouseRelease(int buttons)释放一个或多个鼠标按钮
void mouseWheel(int wheelAmt)在配有滚轮的鼠标旋转滚轮
BufferedImage createScreenCapture(Rectangle screenRect)创建包含从屏幕中读取的像素的图像

第一个例子是鼠标模拟测试，在多线程中每隔1s随机移动鼠标，一共随机6次鼠标闪烁，源码如下：

    public MouseSimulate() {
        random = new Random();
        dim = Toolkit.getDefaultToolkit().getScreenSize();

        try{
            robot = new Robot();
        }catch(AWTException e){
            e.printStackTrace();
        }
    }

    public void run() {
        while(isRunning){
            int x = random.nextInt((int)dim.getWidth());
            int y = random.nextInt((int)dim.getHeight());
            System.out.println("the mouse located in (" + x + "," + y + ")");

            robot.mouseMove(x, y);
            robot.mousePress(InputEvent.BUTTON1_MASK);

            try{
                Thread.sleep(1000);
            }catch(InterruptedException e){
                e.printStackTrace();
            }
        }
    }

    public synchronized void start(){
        isRunning = true;
    }

    public synchronized void stop(){
        isRunning = false;
    }

    public static void main(String[] args){
        MouseSimulate test = new MouseSimulate();

        test.start();
        System.out.println("-----------time start-------------");
        Thread thread = new Thread(test);
        thread.start();

        try{
            Thread.sleep(10000);
        }catch(InterruptedException e){
            e.printStackTrace();
        }

        test.stop();
        System.out.println("-----------time stop--------------");
    }

}

Robot类的方法createScreenCapture可以简单的用于抓取屏幕图片，可以在java应用程序中直接调用该方法抓取屏幕，检测远程电脑屏幕状态，这里参考了java社区的例子，默认构造函数生成后缀为png的文件，可以在第二个构造函数传入其他名称，支持gif和jpg。截图程序源码如下：

/*
* GuiCamera.java
*
* Created on 2007-5-7, 4:18:46
*
* To change this template, choose Tools | Template Manager
* and open the template in the editor.

package cn.edu.yutao;

import java.awt.Dimension;
import java.awt.Rectangle;
import java.awt.Robot;
import java.awt.Toolkit;
import java.awt.image.BufferedImage;
import java.io.File;
import javax.imageio.ImageIO;

/**

* @author Aslan
*/
public class GuiCamera {

    private String fileName;
    private final String defaultFileName = "camera";

    private String format;
    private final String defaultFormat = "png";
    Dimension dim = Toolkit.getDefaultToolkit().getScreenSize();


    public GuiCamera() {
        this.fileName = defaultFileName;
        this.format = defaultFormat;
    }

    public GuiCamera(String fileName, String format) {
        this.fileName = fileName;
        this.format = format;
    }

    public void capture() throws Exception{
        BufferedImage imageScreen = (new Robot()).createScreenCapture(new Rectangle((int)dim.getWidth(), (int)dim.getHeight()));
        String imageName = this.fileName + "." + this.format;
        File file = new File(imageName);
        System.out.println("Save file " + imageName);
        ImageIO.write(imageScreen, format, file);
        System.out.println("Finished!!");
    }

    public static void main(String[] args){
        GuiCamera camera = new GuiCamera("hello", "jpg");
        try{
            camera.capture();
        }catch(Exception e){
            e.printStackTrace();
        }
    }



}

以上程序都在mac os 10.4.8下测试，截图为很漂亮～出现警告是因为某些api在jdk6中已经标记为废弃。
