十六周作业

题目1：编写一个应用程序，利用Java多线程机制，实现时间的同步输出显示。

ThreadTime类

package cc;
import java.util.Date;

public class ThreadTime extends Thread{
    Date date = null;

    public void run() {
        
        while(true){

            System.out.println(new Date());
            try {
                Thread.sleep(1000);
            } catch (InterruptedException e) {
               
                e.printStackTrace();
            }
            
        }
    }

}

Text类

package cc;
public class text {
     public static void main(String[] args) {
           
            ThreadTime t = new ThreadTime ();
            t.start();
            

        }

    }

结果

题目2：编写一个应用程序，利用Java多线程机制，实现猜数字游戏（随机数范围0~100之间的整数）。

package ccut.cn.com;
import java.util.*;
public class test {

    public static void main(String[] args) {
       
        System.out.println("请猜想一个数字，范围在0-500中：");
        Scanner re= new Scanner(System.in);
        Threaddemo num1 = new Threaddemo();
        Thread t = new Thread(num1);
        t.start();
        
        try {
            Thread.sleep(100);
            while(true){
                int num2 = re.nextInt();
                if(num1.getNum()==num2){
                    System.out.println("恭喜你，答对了！");
                    break;
                }
                else if(num1.getNum()>num2){
                    System.out.println("太小了");
                }
                else{
                    System.out.println("太大了");
                }
            }
            
            
        } catch (InterruptedException e) {
            
            e.printStackTrace();
        }

    }

}

package ccut.cn.com;

import java.util.Random;

public class Threaddemo extends Thread{
    int num;
    public int getNum(){
        return num;
    }
    public void setNum(int num){
        this.num = num;
    
    }
    public void run(){
        Random L = new Random();
        num = L.nextInt(500);
    }
    

}
