Ok, this is an extremely stupid question, and I feel retarded for asking, considering how much I've been studying Java. But anyways, here goes.

Let's pretend I've created three classes, Class A, Class B, and Class C. Now in A I create an instance of Class B, let's call it AB. And I modify AB's variables, and invoke methods on it. Object AB holds valuable info, say for a database. Now in C I create another instance of Class B, I'll call it CB. From class C, is there any way I can specific information, such as instance vairable values and other such things of object AB (in class A)?

That's my quesiton. Thanks for any help :)

you can make an interface for this, or you can create accessor methods in AB and call those.
