十六次作业

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。

package shiliu;
import java.util.Date;
public class duoxiancheng {
    public static void main(String[] args) {
        ThreadTime time = new ThreadTime();
        time.start();        
    }
}
 class ThreadTime extends Thread {
    public void run() {
        Date riqi = new Date();       
        while (true) {
            riqi = new Date();
            System.out.println(riqi);
            try {
                Thread.sleep(1000);
            }catch (InterruptedException a) {
                a.getStackTrace();
            }
        }     
    }
}

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 shiliu;
import java.util.*;
public class caishuzi {
    public static void main(String[] args) {
        System.out.println("猜数字游戏现在开始！！！");
        System.out.println("请输入一个0-100之间的数字：");
        Scanner a = new Scanner(System.in);
        Thread shu1 = new Thread();
        Thread t = new Thread(shu1);
        t.start();        
        try {
            Thread.sleep(100);
            while(true){
                int shu2 =a.nextInt();
                if(shu1.getId()>shu2){
                    System.out.println("数字偏小，请重新输入");
                    break;
                }
                else if(shu1.getId()==shu2){
                    System.out.println("哈哈！恭喜你答对啦！！！");
                }
                else{
                    System.out.println("数字偏大，请重新输入");
                }
            }
            
            
        } 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;
    }
}
