代码如下：
import java.awt.*;
import java.awt.image.BufferedImage;
import java.io.File;
import javax.imageio.ImageIO;
public class ScreenCapture {
/**
  * @param args
  */
public static 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, "jpg", new File(fileName));
}
public static void main(String[] args) {
  // TODO Auto-generated method stub
  String str="c:/test.jpg";
  try {
   captureScreen(str);
  } catch (Exception e) {
   // TODO Auto-generated catch block
   e.printStackTrace();
  }
}
}
其中filename是要保存的文件名称
效果如图：
