Need help with this Java coding question, I am supposed to create a program that plays Bulgarian Solitaire as described in the question below.

Question pasted below:

Write the code to implement the game.

Cut and paste your classes into the text area.

You need one class that is the BulgarianSolitaire class which has the variables and methods to play a full game of Bulgarian Solitiraire.

You need another test class which will create a BulgarianSolitaire object from the above BulgarianSolitaire class and call the methods in that object to play the game.

For extra credit add an assertion in Java $($Please include this part$)$
