Question
Your job in this question is to rewrite the IntArrayBag class so that it is generic and can hold any type of object. This means you need to change the data datafield and then correct all of the methods that use it (12 marks). Then, when this is done, write a GUI that allows you to create a bag of dice objects. This means your GUI has the following functionality:
a. Create an empty ArrayBag. It is ok to have it pre-set to use dice as in ArrayBag<Die>.
b. (3 marks) The GUI should have inputs so that you can create dice and add them to the bag. You can use text fields but this might be a good place for radio buttons or a drop down menu since there are only a few valid dice configurations.
c. (3 marks) The GUI should allow you to grab a random die from the bag and roll it. This can be done with a single click
