Java关于Robot类的使用

利用Robot类实现自动操作，实现效果是运行之后鼠标自动定位到整个屏幕坐标系的(635,454)位置，输入wangtianze

 package com.wtz.util;

 import java.awt.AWTException;

 import java.awt.Robot;

 import java.awt.event.InputEvent;

 import java.awt.event.KeyEvent;

 public class RobotTest {

     public static void main(String[] args){

         try {

             Robot robot = new Robot();

             //鼠标移动到坐标(635,454)

             RobotTest.clickMouse(robot, 635, 454, 500);

             int[] keys = {

             robot.delay(500);

         } catch (AWTException e) {

             // TODO Auto-generated catch block

             e.printStackTrace();

         }

     }

     public static void pressKey(Robot robot,int[] keys,int delay){

         for(int i=0;i<keys.length;i++){

             robot.keyPress(keys[i]);

             robot.keyRelease(keys[i]);

             robot.delay(500);

         }

         //处理完需要延迟

         robot.delay(delay);

     }

     public static void clickMouse(Robot robot,int x,int y,int delay){

         robot.mouseMove(x, y);

         robot.delay(500);

         robot.mousePress(InputEvent.BUTTON1_MASK);

         robot.mouseRelease(InputEvent.BUTTON1_MASK);

         robot.delay(delay);

     }

利用Robot类实现监控屏幕,实现效果是运行后每隔50微秒获取当前屏幕图像，显示到JFrame内

 package com.wtz.util;

 import java.awt.AWTException;

 import java.awt.Dimension;

 import java.awt.Graphics2D;

 import java.awt.Rectangle;

 import java.awt.RenderingHints;

 import java.awt.Robot;

 import java.awt.Toolkit;

 import java.awt.image.BufferedImage;

 import javax.swing.ImageIcon;

 import javax.swing.JFrame;

 import javax.swing.JLabel;
