confusion

//let

class A
{
  private int a;

  void useMe()
  {
    ++a;
  }

}

class B extends A
{
  static public void main(String...args)
  {
    new B().useMe();
  }
}

some points:
1.changes in variable "a" means state of an object changes.
2."a" is private so it is not inherited by B.

my Que. is : when "a" changes state of which object's gets changed actually...???as it is not a instance variable of B type,, and there is only one object on heap of B..


i m new to java so please try to help me to learn this language......

a isn't visible by B, but it is inherited by B. The object that gets instantiated will contain an int member variable, and that gets changed.

And welcome to the Ranch!

[Kkush Garg]

you mean private members are inherited but not accessible by subclasses....???

[Javin Paul]

private variables are only accessible inside the class they are declared but Object of B is essentially Object of A and if A changed B automatically changed.

[Martin Petransky]

Isn't it because the VM actually creates three objects on the heap that to certain extent live autonomous lifes ?

Thanks to all......
