java_线程的通信

线程的通信共有三个方法：

　　wait()运行时阻塞，释放锁

　　notify()唤醒阻塞线程

　　notifll()唤醒全部阻塞线程

 public class ThreadTest01 {

     public static void main(String[] args) {
         Test test = new Test();
         Thread thread = new Thread(test);
         Thread thread1 = new Thread(test);
         thread.setName("线程一");
         thread1.setName("线程二");
         thread.start();
         thread1.start();

     }
 }
 class Test implements Runnable{
 /**
  * 打印1到一百两个线程每个线程打印一次
  */
     private int num = 1;
     @Override
     public void run() {
         while (true){
             synchronized (this){

                 if(num<=100){
                     notify();
                     try {
                         Thread.sleep(100);
                     } catch (InterruptedException e) {
                         e.printStackTrace();
                     }
                     System.out.println(Thread.currentThread().getName()+num);
                     num++;
                     try {
                         wait();
                     } catch (InterruptedException e) {
                         e.printStackTrace();
                     }
                 }else{
                     break;
                 }
             }
         }
     }
 }
