I need help to solve this assignment.

CS 115 - Assignment 5

Abstract Class Inheritance

For this homework assignment, you will extend the class PCard and send your new card to a CardTest class to visually display your results. Both PCard and CardTest are provided. You cannot modify either of these files and your code will be tested against them. Your card class must support both rank and suit.

56-Card Deck

Your card class must support the standard 52 cards, plus the Knight. Information about a standard 52-card deck and the knight can be found at the following Wikipedia entries:

https://en.wikipedia.org/wiki/Standard_52-card_deckj

https://en.wikipedia.org/wiki/Knight_(playing_card)

Testing Output

Create a unit test to validate that all required card types are valid with your card class. You must also create a main method that uses the method run in CardTest to visually display results for a single card.
