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 {

//鼠标移动到坐标(635,454)

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.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; /**
