Java基础--多线程--练习（过隧道）

编写多线程应用程序，模拟多个人通过一个山洞：

package com.Train;

public class MuThreadTest{

public static void main(String[] args) {
// TODO Auto-generated method stub
//创建一个山洞
Tunnel tul = new Tunnel();

//十个人过山洞
Thread p1 = new Thread(tul,"p1");
Thread p2 = new Thread(tul,"p2");
Thread p3 = new Thread(tul,"p3");
Thread p4 = new Thread(tul,"p4");
Thread p5 = new Thread(tul,"p5");
Thread p6 = new Thread(tul,"p6");
Thread p7 = new Thread(tul,"p7");
Thread p8 = new Thread(tul,"p8");
Thread p9 = new Thread(tul,"p9");
Thread p10 = new Thread(tul,"p10");
p1.start();
p2.start();
p3.start();
p4.start();
p5.start();
p6.start();
p7.start();
p8.start();
p9.start();
p10.start();
}
}

class Tunnel implements Runnable{
private int crossedNum = 0;
//override
public void run(){
Cross();
}

//同步函数--同步锁为this，即main()中创建的tul。

public  synchronized void Cross(){
try {
Thread.sleep(5000);
} catch (InterruptedException e) {
e.printStackTrace();
}
crossedNum++;
System.out.println(Thread.currentThread().getName()+" have Crossed the tunnel !"+" This is "+crossedNum+"th");

}
}
