如何实现控制台清屏？（借鉴）

package 清屏;

import java.awt.AWTException;
import java.awt.Robot;
import java.awt.event.InputEvent;
import java.awt.event.KeyEvent;

public class 清屏 {

    public static void main(String[] args) throws AWTException {
        
   System.out.println("5554454544545");
       clear();
      
    }
    public static void clear() throws AWTException
    {
        Robot r = new Robot();
        r.mousePress(InputEvent.BUTTON3_MASK);       // 按下鼠标右键
        r.mouseRelease(InputEvent.BUTTON3_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);       

    }
}
