线程的常用方法

1.start()

线程调用该方法将启动线程，使之从新建状态进入就绪队列排队。

2.run()

3.sleep()

4.isAlive()

线程处于新建状态时，线程调用isAlive()方法返回false。

public class ClassRoom implements Runnable {
    Thread student, teacher;
    ClassRoom()
    {
        teacher = new Thread(this);
        student = new Thread(this);
        teacher.setName("王教授");
        student.setName("张三");
    }

    @Override
    public void run() {
        // TODO Auto-generated method stub
        if(Thread.currentThread() == student)
        {
            System.out.println(student.getName() + "正在睡觉, 不听课");
            try {
                Thread.sleep(1000*100);
            } catch (InterruptedException e) {
                // TODO Auto-generated catch block
                System.out.println(student.getName() + "被老师叫醒了");
            }
        }
        else if(Thread.currentThread() == teacher)
        {
            for(int i = 1; i <= 3; i++){
                System.out.println("上课");
                try {
                    Thread.sleep(500);
                } catch (InterruptedException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                }
            }
            student.interrupt();
        }
    }

}

运行

public class Test03 {

    public static void main(String[] args) {
        // TODO Auto-generated method stub
        ClassRoom room6501 = new ClassRoom();
        room6501.student.start();
        room6501.teacher.start();
    }

}

运行结果如下所示：
