多线程下，两个线程交替打印0 -100，使用wait()和notify()

public class ThreadTest {
//    public static int i = 0;
    private static final Object lock = new Object();//锁
    public static class Thread1 extends Thread{
        @Override
        public void run(){
            for (int i = 0; i <=100; i = i+2) {
                synchronized (lock){
                    lock.notify();//唤醒，获取锁
                    System.out.println(Thread.currentThread().getName()+" "+i);
                    try{
                        lock.wait();//打印之后等待,释放锁，t2拿到锁开始工作
                    }catch (Exception e){
                        e.getLocalizedMessage();
                    }
                }
            }
        }
    }
    public static class Thread2 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);
                    try{
                        lock.wait();//打印之后等待
                    }catch (Exception e){
                        e.getLocalizedMessage();
                    }
            }
        }
    }

    @Test
    public void Test(){
            try {
                new Thread1().start();
                new Thread2().start();
                Thread.sleep(200);//这里不加sleep在IDEA中运行可能会造成程序提前结束打印不全
            }catch (Exception e){
                e.getLocalizedMessage();
            }
    }
}
}
