    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。

    代码:

    package Example12_12;
    import java.util.Date;
    class ThreadTime implements Runnable{
        Date date = null;
        public void run() {
            while(true) {
            date = new Date();
            System.out.println(date);
            try {
                Thread.sleep(1000);
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
            }        
        }
    } 
    public class Test12_19 {
        public static void main(String[] args) {
            // TODO Auto-generated method stub
            Thread time = new Thread(new ThreadTime());
            time.start();
        }
    
    }

    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 Example12_12;
    import java.util.*;
    class Threadnum extends Thread{
        Thread output;
         int num1,num2;
        Threadnum(){
            output = new Thread(this);
         }
        public void run() {
            Random n = new Random();
            num1 = n.nextInt(100);
            try {
                output.sleep(4000);
                Judge();
            } catch (InterruptedException e) {
                e.printStackTrace();
            }        
        }
        public void Judge() {
            while(true){
                Scanner reader = new Scanner(System.in);
                num2 = reader.nextInt();
                if(num1==num2) {
                System.out.println("猜对了正确数字为:"+num1);
                break;
            }else if(num1>num2) {
                System.out.println("猜小了");
                
            }else {
                System.out.println("猜大了");
            }
            }
            
        }
    }
    public class Test12_19_2 {
    
        public static void main(String[] args) {
            // TODO Auto-generated method stub
            System.out.println("请输入猜测的数字");
            Threadnum num = new Threadnum();
            num.output.start();
        }
    
    }
