第16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。

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）

代码：

package edu.ccut;
import java.util.Date;
public class Test_1 {

    public static void main(String[] args) {
        ClockThread clockThread = new ClockThread();
        clockThread.start();
        System.out.println("okk");
 
    }
}    
    class ClockThread extends Thread {
        public void run() {
            super.run();
            while (true) {
                System.out.println(new Date());
                try {
                    Thread.sleep(1000);
                } catch (InterruptedException e) {
                    e.printStackTrace();
                }
            }
        }
    }

运行结果：

代码：

package edu.ccut;
import java.util.*;

public class Test_2 {
    public static void main(String[] args) {  
        Scanner input=new Scanner(System.in);
        Num num1=new Num();
        Thread thread=new Thread(num1);
        thread.run();
        System.out.println("请输入你猜的数字");
        try {
            Thread.sleep(10);
            while(true) {
                Thread.sleep(10);
                thread.interrupt(); 
                int num2=input.nextInt();
                if(num1.getNum()==num2) {
                    System.out.println("猜对了");
                    break;
                }
                else if(num2<num1.getNum()){
                    System.out.println("猜小了");
                }else
                    System.out.println("猜大了");
            }
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
    }
 
}
class Num implements Runnable{
    int num;
    public synchronized void run() {
        Random n= new Random();
        num=n.nextInt(100);
    }
    public int getNum() {
        return num;
    }
    public void setNum(int num) {
        this.num=num;
    }
}

运行结果：
