java编程示例，比较实用的

class A implements Runnable { Thread student,teacher; A() { teacher=new Thread(this); student=new Thread(this); teacher.setName("老师"); student.setName("张三"); } public void run() { if(Thread.currentThread()==student) { try{ System.out.println(student.getName()+"正在睡觉，不听课"); Thread.sleep(1000*60*60); } catch(InterruptedException e) { System.out.println(student.getName()+"被老师叫醒了"); } System.out.println(student.getName()+"开始认真听课"); } else if(Thread.currentThread()==teacher) { for(int i=1;i<=3;i++) { System.out.println("上课!"); try{ Thread.sleep(500); } catch(InterruptedException e){} } student.interrupt(); //吵醒student } } } public class app7_4 { public static void main(String args[]) { A a=new A(); a.teacher.start(); a.student.start(); //china.beijing.getSong();内部类 } }
