java中类中多个Synchronized方法

类中多个Synchronized方法  

下面给出一个例子，说明一个class中有两个方法synchronized的情况。它们互相阻挡的用法和上面的“一个方法有synchronized”的情况是一样的。

例1.9.5:

class A {

    public synchronized void f1() {

        for (int i = 0; i < 3; i++) {

            try {

                Thread.sleep(1000);

            } catch (Exception e) {

            }

            System.out.println("f1 i = " + i);

        }

    }

    public synchronized void f2() {

        for (int i = 0; i < 3; i++) {

            try {

                Thread.sleep(1000);

            } catch (Exception e) {

            }

            System.out.println("f2 i = " + i);

        }

    }

}

class MyThread1 extends Thread {

    A a;

    public MyThread1(A a) {

        this.a = a;

    }

    public void run() {

        a.f1();

    }

}

class MyThread2 extends Thread {

    A a;

    public MyThread2(A a) {

        this.a = a;

    }

    public void run() {

        a.f2();

    }

}

public class TestMark_to_win {

    public static void main(String[] args) {

        A a = new A();

        Thread t1 = new MyThread1(a);

        Thread t2 = new MyThread2(a);

        t1.start();

        t2.start();

    }

}
