编写多线程应用程序，模拟多个人通过一个山洞：
1、 这个山洞每次只能通过一个人，每个人通过山洞的时间为5秒
2、随机生成10个人，同时准备过此山洞，显示一下每次通过山洞人的姓名
MuThreadTest.java
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 //代码效果参考：https://v.youku.com/v_show/id_XNjQwMDE0NDc1Ng==.html
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();
}
//代码效果参考：https://v.youku.com/v_show/id_XNjQwNjU5MTY3Ng==.html
