How do I check to see if two Lists are the same?But is there a way to check it within my code? Like if the dog description is brown and spotted and the user picks a white and spotted dog is there a method or something that would return false in that case (descriptions are already set in Lists - one for projected pet and one for the pet the owner picks)?

Second list:
In Mannequin class (extends Actor) -
You drag the items onto the mannequin so the first list is the items you are supposed to drag onto the mannequin and the second list is the items the player put on the mannequin so I need a way to check to see if the two lists are the same to make sure the player put the right items on the mannequin.

}Okay -- your lists will never contain the same things. The reason being is that you create and add items to one list (in the PackingList class), then, you acquire the other list by using 'getIntersectingObjects' (in the Mannequin class). These lists may contain similar type items, but they will not be the same items (a Tank actor in one list is not the same Tank actor in the other list). Probably best is to create one of each item to start with. Save a reference to each and add a getter method for each. Then the world can get and add each into itself and the PackingList class can add their references to its list. That way, the intersecting objects will be the exact same items.
