Question 2: Deck of cards (20 marks) In this question you will complete the Hand class and SortCards class. Spend some time analysing the Card, Deck, Hand and SortCards classes. SortCard class [3 marks] Complete the comparator method compare so that the card objects are compared as follows: Where 01 has a higher value property than o2 return 1. Where 01 has a lower value property than o2 return -1; Where the value property of both of and o2 is the same return 0. Hint: Card has a method getNumericValue that will convert the String value of the card to an integer for easy comparison. In this implementation Aces are the highest value. Hand class [17 marks] Complete the getHandRank method. This should return the correct string from the ranks array of Hand based on the cards that have been dealt. Base your determination of the rank on the classic poker hands. See the code and the image below for a guide to examples of the 10 ranks these. Using the SortCards class you completed above the cards of the hand are sorted. This will make this task much easier! Again, use the main method in CardMain to test your code as you develop your solution. You should also make use of the dealSpecific Card method in deck. This will help you to deal specific hands that you can check your code against.
