Question
Using Java complete a main method for the following code.
The main program (aka test program) should build an ArrayList of stationary objects and an ArrayList of moveable objects. It should build an ArrayList of collectable objects for each good guy’s backpack. The main program should go through all objects in each ArrayList and call their common methods (e.g., display(), move(), fight(), etc.).

Certain parts of the code has been optimized to meet the explicit requirments of the main function. Let me know if you like the code!
