How to get the object reference of a class

I have made two JAVA classes classA and classB in the same package. The classA consists of two labelFields开发者_如何学Python and a button. And then I made 5 objects of classA inside classB. Now when click on the button of any object of classA which is inside classB. The logic for buttons click event i have written it inside classA. Now how can classA know which object's button was clicked from classB. I am developing an application for blackberry.

Class A will only know what you tell it. Class B can call the correct method of Class A for a given button, or pass the information about which button was clicked to Class A.

More information about your classes, and perhaps some code, would be helpful.

I'd say use Implicit invocation. Wikipedia does a good explanation http://en.wikipedia.org/wiki/Implicit_invocation

If this is what you want, I can add general java code for implementing it.
