使用 java.awt.Robot 可以抓取屏幕

import java.awt.AWTException; 
import java.awt.Robot; 
import java.awt.Rectangle; 
import java.awt.Toolkit; 
import java.awt.image.BufferedImage; 
import java.io.*; 
import javax.imageio.ImageIO; 
 
class ScreenCapture { 
  public static void main(String args[]) throws 
           AWTException, IOException { 
     // capture the whole screen 
     BufferedImage screencapture = new Robot().createScreenCapture( 
           new Rectangle(Toolkit.getDefaultToolkit().getScreenSize()) ); 
 
     // Save as JPEG 
     File file = new File("screencapture.jpg"); 
     ImageIO.write(screencapture, "jpg", file); 
 
     // Save as PNG 
     // File file = new File("screencapture.png"); 
     // ImageIO.write(screencapture, "png", file); 
  } 
}

可以指定要抓取的区域

BufferedImage screencapture = new Robot().createScreenCapture( 
   new Rectangle( 15, 15, 150, 150));

可以抓取指定控件：

BufferedImage image = new Robot().createScreenCapture(  
   new Rectangle( myframe.getX(), myframe.getY(),  
                  myframe.getWidth(), myframe.getHeight() ) );
