Java作业五（下）

题目

有3个线程: student1、student2和teacher，其中student1准备睡10分钟后再开始上课,其中student2准备睡1个小时后再开始.上课。Teacher在输出3句“上课”后,吵醒休眠的线程student1，student1被吵醒后,负责再吵醒休眠的线程student2。(即P394 4.编程题第(2)题)

代码

package homework;

class ClassRoom implements Runnable{
	Thread student1,student2,teacher;
	public ClassRoom(){
		student1 = new Thread(this);//必须有this
		student2 = new Thread(this);
		teacher = new Thread(this);
		student1.setName("student1");
		student2.setName("student2");
		teacher.setName("teacher");
	}
	public void run() {
		if(Thread.currentThread() == student1) {
			try {
				System.out.println(student1.getName()+"正在睡觉");
				Thread.sleep(1000*10*60);
			}catch(InterruptedException e) {
				System.out.println(student1.getName()+"被teacher叫醒");
			}
			System.out.println(student1.getName()+"开始听课");
			student2.interrupt();
		}
		else if(Thread.currentThread() == student2) {
			try {
				System.out.println(student2.getName()+"正在睡觉");
				Thread.sleep(1000*60*60);
			}catch(InterruptedException e) {

				try {
					Thread.sleep(10);
