Cheers, let's suppose I have 3 different classes: A,B and C. A is abstract with a class of print() which is abstract again. B is a sub-class of A, and is again abstract. C is a sub-class of B, and here we want to implement print.
So in code (suppose they are in different files for the public part):
public abstract class A {
public abstract void print();
}
public abstract class B extends A {
// public abstract void print();
}
public class C extends B {
public void print() {
// some code here
}
}
What difference would it make if we redefined the print() function in B as abstract, and if we didn't? I see that in the compilation nothing changes, and in both ways it works correctly, but is there a reason one would be preferred over the other? Thanks =)
