Question

Write a console application called PlayingCards that has 4 classes: PlayingCards, Deck, Cards, Card. This application will be able to create a deck of cards, shuffle it, sort it and print it.

Use the following class diagrams to code your application.

Use the following code for the PlayingCards class

public class PlayingCards{ public static void main(String[] args){                 System.out.println("Playings Cards");                 Deck deck = new Deck();                 deck.create();                 System.out.println("Sorted cards");                 deck.sort();                 deck.showCards();                 System.out.println("Shuffled cards");                 deck.shuffle();                 deck.showCards(); } }
