My brother does not have access to a correction institution but he is learning java. He has the "Java How to program 10th edition early objects". He is stuck on exercise 7.30 and 7.31. He needs to know what needs to be added to the deck of cards.java file to make java understand hands in poker. He needs the updated source file for 7.30 and 7.31

The book's question: Card shuffling and dealing Modify the application of figure 7.11 (an application that created card objects in a deck of card objects) to deal a 5 card poker hand. The modify class DeckOfCards to include methods that determine whether a hand contains a a pair b- two pairs c- three of a kind d- four of a kind e- flush f- straight g- full house

His question: Classes for card in DeckOfCard are made but I am unable to figure out the methods to make the computer know that a hand has been made. Programming language is Java.

This is the complete question
