如何使用Java代码实现抓屏呢？

实现思路:
　　借助Toolkit类即可实现抓屏的效果

package com.java265.other;
import java.awt.Dimension; 
import java.awt.Rectangle; 
import java.awt.Robot; 
import java.awt.Toolkit; 
import java.awt.image.BufferedImage; 
import javax.imageio.ImageIO; 
import java.io.File; 
 
public void captureScreen(String fileName) throws Exception { 
  Dimension screenSize = Toolkit.getDefaultToolkit().getScreenSize(); 
  Rectangle screenRectangle = new Rectangle(screenSize); 
  Robot robot = new Robot(); 
  BufferedImage image = robot.createScreenCapture(screenRectangle); 
  ImageIO.write(image, "png", new File(fileName)); 
}
