Deadline fast approaching, need help

Question

If I have 2 InternalFrames that can call the same class,
How can I find out which Internalframe the call came from.
Thanks

Answer 1

this is assuming that the program structure that you are looking for is like this:
The two InternalFrames are seperate instantitation of the same class, and that they call the other class seperatley.
that those seperate instantiations of the other class have knowledge of each calling class, and that the calling class has the ability to be identified.
I would use a String to store "name" for the class and make sure it is not static. If it is then when you change one you change them all. Then you can make set/get methods for that String, and you can have a constructor that can set the "name" variable too.
If I understand your question right, then your InternalFame class will have to pass a reference to themselves to the class constructor/method that they are calling. Otherwise the class the was called by the two InternalFrames would not have anyu sort of handle to reference the InternalFrame class.
Finally, if you want the infromation about the calling object inside of the called class to be visible to each instantiation of that class then it should store the InternalFrame refrence in an static data-structure that can store multiple objects (ie Vector, Object[], ...)
to sum it up:
--in InternalFrame use an identifier variable (your choice) but don't use static variables if the 2 classes are of the same type
--In InternalFrame when you are constructing the "other class" pass a reference of the the "calling class" to the class that is getting called.
--in the "other class" store the references in a static variable that can hold multiple objects. 
hope this helps.
