wait和notify简单学习

public static class Thread1 extends Thread{
    @Override
    public void run() {
        synchronized (lock){
            System.out.println("this is "+Thread.currentThread().getId());
            try {
                //模拟工作1
                Thread.sleep(1000);
                System.out.println(Thread.currentThread().getId()+" begin to wait");
                lock.wait();
                System.out.println(Thread.currentThread().getId()+" get lock and restart");
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
            System.out.println(Thread.currentThread().getId()+" work complete");
        }
    }
}
public static class Thread2 extends Thread{
    @Override
    public void run() {
        synchronized (lock){
            System.out.println("this is "+Thread.currentThread().getId());
            try {
                //模拟工作2
                Thread.sleep(2000);
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
            System.out.println(Thread.currentThread().getId()+" egin to notify");
            lock.notify();
            try {
                Thread.sleep(1000);
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
            System.out.println(Thread.currentThread().getId()+" work complete");
        }
    }
}

public static void main(String[] args) throws InterruptedException {
    new Thread1().start();
    new Thread2().start();

}

}

运行结果
this is 18
18 begin to wait
this is 19
19 egin to notify
19 work complete
18 get lock and restart
