Question

If I have a class SubOfParent which is a sub-class of Parent, and two methods:

 public static void doStuff(Parent in) {}

 public static void doStuff(SubOfPArent in) {}

why does the first doStuff get called when I pass a SubOfParent type object?

Thanks for any insight on this!

Answer 1

Parent p = new SubOfParent();
SubOfParent s = new SubOfParent();

doStuff(p); //calls doStuff(Parent in)
doStuff(s); //calls doStuff(SubOfParent in)

//If you're working with a parent but need to call the subclass, you need to upcast it.
dostuff(p as SubOfParent);
