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() ) );
