Class members don't override via inheritance in Java?

Question

Consider following code:
class A
protected int v=1;
void print()
System.out.println(v);
class B extends A
protected int v=2;
public class m
public static void main(String args[])
B kl=new B();
kl.print();
What do you think, what should be the program's output?
It is "1" - I think in C++ it would be "2" (I am not sure of this). Why the member variable "v" doesn't override the one from parent class in "print" method? Do you think it is ok?
Consider changing B class definition to this:
class B extends A
protected int v=2;
B() { v=3; }
The output is still "1",
but:
class B extends A
// protected int v=2;
B() { v=3; }
And the output is "3".
So we have two different variables: A.v and B.v.
Shouldn't be only one there, depending on the class of the object?

Answer 1

Considder the following code.
public class a
   int a;
   public a()
      a = 1;
   public int a()
      return a;
   public int a(a a)
      a.a = a.a++;
      if(this.a == a.a)
         return a();
      else
         return a.a;
}Are you surprised that it actually compiles? Do you have any doubt about the behavour? Do you think it is smart to reuse the symbol a? Do you think it is smart to reuse the symbol v? Because that is what you do. You have two different integers, both with the name v. Then it gets confusing. My advice: Give them different names!
