多线程下，两个线程交替打印0 -100，使用wait()和notify()

 public class ThreadTest{
     private static final Object lock = new Object();

    static  class ThreadA extends Thread{
         @Override
         public void run() {
             for (int i = 0; i < 100; i = i+2) {
                synchronized (lock){
                    lock.notify();
                    System.out.println(Thread.currentThread().getName()+" "+i);
                    try {
                        lock.wait();
                    } catch (InterruptedException e) {
                        e.printStackTrace();
                    }

                }
             }
         }

     }

     static  class ThreadB extends Thread{
         @Override
         public void run() {
             for (int i = 1; i < 100; i = i+2) {
                 synchronized (lock){
                     lock.notify();
                     System.out.println(Thread.currentThread().getName()+" "+i);

                     }

                 }
             }
         }

     }

     public static void main(String[] args) {
         new ThreadA().start();
         new ThreadB().start();

 }
