Question 2: Classes

Part A: Write the complete HiddenWord class, including any necessary instance variables, its constructor, and the method, getHint, described above. You may assume that the length of the guess is the same as the length of the hidden word.

        }
        
        scanner.close();

PokerHand.main(null);

Your hand:
6H
7S
AD
5H
8C
Enter your guess (flush, straight, high card, etc.): 
Your guess: Flush
Incorrect guess or you don't have a Flush.

Question 2 Part A explanation

In this example, the PokerHand class creates a guessing game where the user tries to guess a poker hand pattern. The hiddenPattern is the pattern to be guessed and the getHint method gives feedback on the user’s guess. The feedback is simplified to symbols to indicate correct characters in correct hands.

The main method demonstrates how the class might be used with a user guess. For PLACE.com’s Poker feature, we could integrate user input and a more sophisticated method for generating and evaluating poker hands
