类的继承day01

1.   以下代码的执行结果是   （C）

public class Person {
         String name="Somebody";
         String say(){
             return "It's Somebody speaking";
         }
}


public class Man extends Person{
         String name="Mike";
         String say(){
             return "It's Mike speaking";
         }
}

public class Company {
              public static void main(String[] args) {
                new Company().sayhi();
            }
              
           void sayhi(){
               Person m=new Man();
               System.out.println(m.name+" "+m.say());
           }
            A Somebody It's Somebody speaking
            B Mike It's Somebody speaking
            C Somebody It's Mike speaking
            D Mike It's Mike speaking
}

考察的知识点 

1）父类声明指向子类对象，该引用只能父类中定义的方法和属性。

2)  如果子类中重写了父类的方法，那么在调用这个方法的时候，将会调用子类中的方法。
