面向对象的Java : how subclass-object use method from superclass (that method has been Override)

Question

我有这个例子:

public class Inheritance {

    public static class Animal {        
        public void Scream() {
            System.out.println("I'm an animal");
        }       
    }

    public  static class Mammal extends Animal{
        public void Scream(){
            System.out.println("I'm a mammal");
        }       
    }

    public  static class Tiger extends Mammal{
        public void Scream(){
            System.out.println("I'm a tiger");
        }       
    }

    public static void main (String[] args){

        Animal tiger = new Tiger();
        tiger.Scream();
    }

}

当然，我会收到:“我是老虎”。但是，我不知道如何打印“我是哺乳动物”或“我是动物”

@: 请回答我的子问题:如果是 Tiger 类，Tiger 的父类(super class)是什么。 哺乳动物 还是 动物 ?

请帮助我:)

谢谢:)

Answer 1

这是代码示例:

public class Inheritance {

  public static class Animal {        
      public void Scream() {
          System.out.println("I'm an animal");
      }       
  }

  public  static class Mammal extends Animal{
      public void Scream(){
          super.Scream();
          System.out.println("I'm a mammal");
      }       
  }

  public  static class Tiger extends Mammal{
      public void Scream(){
          super.Scream();
          System.out.println("I'm a tiger");
      }       
  }

  public static void main (String[] args){
      Animal tiger = new Tiger();
      tiger.Scream();
  }

}
