(8)线程Thread演示

package com.xuan.thread;/*多线程演示，是Threads子类*/public class Threads extends Thread{String mesg;int count;/*run用于输出信息，共有count次*/public void run(){while(count-->0){println(mesg);try{Thread.sleep(100);//100msec}catch(InterruptedException e){return ;}}println(mesg+" all done");}void println(String s){System.out.println(s);}/*构造一个Threads对象 * @param m要显示的信息 * @param n要显示的次数 * */public Threads(String m,int n){count=n;mesg=m;setName(m+" return Thread");}/*主程序，Thread类的测试程序*/public static void main(String[] args) {//可以写入：new Threads("Hello from X",10).run();//也可以写成：new Threads("Hello form Y",15).run();//但非多线程的！new Threads("Hello from X",10).start();new Threads("Hello from Y",15).start();}}
