该操作时让机器人模拟人手按快捷键来实现的

void clear() {

		   try {
				
				
					Robot r = new Robot();
					r.mousePress(InputEvent.BUTTON3_DOWN_MASK);		//按下鼠标右键
					r.mouseRelease(InputEvent.BUTTON3_DOWN_MASK);	//释放鼠标右键
					r.keyPress(KeyEvent.VK_CONTROL);				//按下Ctrl键
					r.keyPress(KeyEvent.VK_R);						//按下R键
					r.keyRelease(KeyEvent.VK_R);					//释放R键
					r.keyRelease(KeyEvent.VK_CONTROL);				//释放Ctrl键
					r.delay(100);
				
	
		   }
		   catch (AWTException e) {
			   e.printStackTrace();
			 }

	}

然后import以下包：
import java.io.*;
import java.awt.Robot;
import java.awt.AWTException;
import java.awt.event.InputEvent;
import java.awt.event.KeyEvent;
