Calling overloaded inherited methods using super class reference

Question

I do not understand this Java behavior. I have two classes:

class C1 {
    public void m1(double num) {
        System.out.println(\"Inside C1.m1(): \" + num         


        

Answer 1

If you call c.m1(10.0) it will call the method of the ancestor as you were expecting at first.

You're doing method overloading in your example (that is adding more methods with the same name and different signature) instead of method overriding (that is changing the implementation of an ancestor's method at a descendent by redeclaring it with the same signature, AKA same name and same type of result and of method arguments - argument names shouldn't matter).
