抽象类_2

四个类，体现类的继承；抽象类的抽象和具像

//顶级父类，一切存在的抽象
public  abstract class Things {
    public abstract void grow();
    public abstract void name();
}

//活的
public abstract class Living extends Things {
    @Override
    public void grow() {
        Log.d(TAG, "Living things can grow.");
    }
    abstract void move();
}

//动物
public abstract class Annimal extends Living{
    @Override
    void move() {
        Log.d(TAG, "Annimal can move");
    }
    abstract void moveStyle();
}

//狗 
public class Dog extends Annimal{
    //实现顶级父类的name方法
    @Override
    public void name() {
        Log.d(TAG, "name: Dog ");
    }
 //实现直接父类的moveStyle方法
    @Override
    void moveStyle() {
        Log.d(TAG, "moveStyle: run");
    }
}
