Is it not against OO concept?

[Geethakrishna Srihari]

The following code compiles:
class A
{
private int i;
public void modifyOther(A a1)
{
a1.i = 20;
}
}

The object has permission to use other object's private member ; it might be of same class - but is it not against OO? But this code compiles?

[Ernest Friedman-Hill]

Encapsulation in Java is class-based, not object based. C++ is the same way. Some languages -- Ruby, and Python, I think, too -- have object-based encapsulation. I don't think one is more object-oriented than the other, really.
