JAVA - 线程之wait(), notify()实例

package intro.thread;

class Test {
    public synchronized void w() {
        System.out.println("go into w");
        try {
            wait(5000);
        } catch (InterruptedException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        System.out.println("get out w");
        notify();
    }

    public synchronized void n() {
        System.out.println("go into n");
        try {
            wait();
        } catch (InterruptedException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        System.out.println("get out n");
    }
}

class ThreadA3 extends Thread {
    Test t = null;

    public ThreadA3(Test t) {
        this.t = t;
    }

    public void run() {
        t.w();
    }
}

class ThreadA4 extends Thread {
    Test t = null;

    public ThreadA4(Test t) {
        this.t = t;
    }

    public void run() {
        t.n();
    }
}

public class ThreadTest3 {
    public static void main(String[] args) {
        Test t = new Test();
        ThreadA3 a3 = new ThreadA3(t);
        ThreadA4 a4 = new ThreadA4(t);
        a3.start();
        a4.start();
    }
}

结果：

开始输出

go into w

go into n

过5秒后输出

get out w

get out n
