Java线程实现浏览器实时时钟

11. 利用线程方法编写 JApplet 程序，实现在浏览器端实时动态显示本地系统时钟

//Programme Name Watch.java import java.applet.Applet;

import java.awt.*;

import java.text.DateFormat;

import java.util.*;

public class Watch extends Applet { public void paint(Graphics g){

Date d=new Date();

DateFormat ldf=DateFormat.getDateTimeInstance(DateFormat.LONG,DateFormat.LONG);

//System.out.println(" 现在系统时间是(long):"+ldf.format(d));

String time=ldf.format(d).toString();

g.drawString(time,100,100); try{

Thread.sleep(1000);

}catch (InterruptedException e){}

repaint();

}
