override 重写

//override:子类继承父类，子类重写父类的方法

public class override {
    public static void main(String[] args) {
        horse h = new horse();
        vehicle v = new vehicle();
        v.run();
        v.stop();
        h.run();
    }
}

class vehicle{
    public void  run()
    {
        System.out.println("父类马儿在奔腾！");
    }

    public void stop()
    {
        System.out.println("父类马儿停下吃草！");
    }
}

class horse extends vehicle{
　　@override
    public void run() {
        System.out.println("马儿不仅跑还要吃草！");
    }
}
