线程

 最近在学Java中的线程，今天老师刚讲了一道demo自己还没试，自己写了一下，程序代码如下，可能有写错误！

//student1睡20分钟 student2睡40分钟.. teacher叫醒student1，叫四句“上课了”，然后student1叫醒student2

class sleep implements Runnable{

Thread student1,student2,teacher;

public sleep(){//定义一个构造函数，用来显示对应的哪一个对象

student1=new Thread(this,"student1");

student2=new Thread(this,"student2");

teacher=new Thread(this,"teacher");

}

public void run(){

while(true){

if(Thread.currentThread().getName().equals(student1));

try {

Thread.sleep(20*60*1000);

System.out.println("我是student1");

} catch (InterruptedException e) {

System.out.println("我是student1，被teacher叫醒!");

student2.interrupt();

}

if(Thread.currentThread().getName().equals(student2));

try {

Thread.sleep(40*60*1000);

System.out.println("我是student2");

} catch (InterruptedException e) {

System.out.println("我是student2，被student1叫醒!");

}

if(Thread.currentThread().getName().equals(teacher));

for(int i=0;i<3;i++){

System.out.println("ring!!!");

}

try {

Thread.sleep(500);

} catch (InterruptedException e) {

System.out.println("我是teacher，叫醒student1!");

student1.interrupt();

}

}

}

}

public class sleepDemo {

public static void main(String []args){

sleep s1=new sleep();

s1.student1.start();

s1.student2.start();

s1.teacher.start();

}

 

}
