代码简单说明：可以在1024*768的屏幕分辨率下关掉一个最大化的IE窗口。


import java.awt.*;
import java.awt.event.*;

/**this class will close an maxmimum IE window in the 1024*768's screen resolution's machine.*/
public class Robot04{
   public static void main(String[] args)
                             throws AWTException{
  Robot robot = new Robot();
  robot.mouseMove(1005,10);
  robot.delay(2000);
  robot.mousePress(InputEvent.BUTTON1_MASK);
  robot.delay(2000);
  robot.mouseRelease(InputEvent.BUTTON1_MASK);
   }//end main

}//end class Robot04
