Hi,

Class A extends class B like so:

public class A extends B{}

Why is class B’s constructor called? I thought when A extends B, A gets all of B’s methods and variables, great; but I don’t need the constructor called because class B has already been created. I just want class A to inherit all of B’s methods and variables. Can a class have two constructors, so when I extend class B an empty constructor is called but when I instantiate it the constructor with code is called?

I feel like I’m missing something here. :puzzled:

Thanks,
