Java “trick”, redefining daughter class member

Question

I\'m training for a Java exam, and I\'ve come across something I don\'t understand in last year subject. Here is the code

class Mother {
    int var = 2;

    in         


        

Answer 1

m = new Daughter();

Though you have created a daughter object, you are referring that object with Mother m reference. So, any call using m will call the Mother class members, not daughter's
