Programming Project 3.1 on page 64 from Java Software Structures: Designing and Using Data Structures 4th edition. "Complete the implementation of the ArrayStack class presented in this chapter. Specifically, complete the implementations of the isEmpty, size, and toString methods."

Include one or more Exception classes in the project so that you can throw an exception if an object is null or there is an error.

For this problem, you will have to write TWO classes. One using the Player class and another class that is meaningful to you.

In the driver, you will create objects of these classes, and manipulate them using two stacks, with one for each class.

You have to make sure you test all methods in the Stack class meaningfully.

You also have to make sure you test all methods in the two classes you have written while manipulating the objects using the Stack data structure, meaningfully.

In the Driver, you must test all methods in a self-documentary way. When the output is displayed, it should be self-explanatory. The reader should not have to look at your code to understand the output.

Programming Language is Java. Can you help me figure out this one? I would very appreciate it. Please and thank you!

Edit: I actually don't know the existing code for this. I'm just having a hard time figuring this out on my own, as the screenshots below are sample outputs that I'm having trouble understanding. If I need to resubmit this question again, then let me know.
