Consider a guessing game in which a player tries to guess a hidden word. The hidden word contains only capital letters and has a length known to the player. A guess contains only capital letters and has the same length as the hidden word. After a guess is made, the player is given a hint that is based on a comparison between the hidden word and the guess. Each position in the hint contains a character that corresponds to the letter in the same position in the guess. The following rules determine the characters that appear in the hint.

Guess Letter	Hint Character
In same position and also in hidden word	Matching letter
In hidden word, but in different position	“*”
Not in hidden word	”+”

Instructions:

The HiddenWord class will be used to represent the hidden word in the game.
The hidden word is passed to the constructor.
The class contains a method, getHint, that takes a guess and produces a hint.

Example:

Suppose the variable puzzle is declared as follows:

The following table shows several guesses and the hints that would be produced:

Call to `getHint`	String returned
puzzle.getHint(“AAAAA”)	“+A+++”
puzzle.getHint(“HELLO”)	“H**”
puzzle.getHint(“HEART”)	“H++”
puzzle.getHint(“HARMS”)	“HAR*S”
puzzle.getHint(“HARPS”)	“HARPS”

This table demonstrates the correspondence between the guess and the hint produced by the getHint method based on the hidden word.

Reflection.

THis was where I found most of my suceses in and was the question I was most undrstood as it tested my ability to create a class with approprate fields and instance vairable, constructors that intialized my variables and methods that created the matching game, however I had to reference previous lessons to understand the implementation of a string builder to add the correct vairables to match up the guess

public class HiddenWord {
    private String hiddenWord;

    public HiddenWord(String word) {
        this.hiddenWord = word;
    }

    public String getHint(String guess) {
        StringBuilder hint = new StringBuilder();
        for (int i = 0; i < hiddenWord.length(); i++) {
            if (guess.charAt(i) == hiddenWord.charAt(i)) {
                hint.append(hiddenWord.charAt(i)); // Correct letter in correct position
            } else if (hiddenWord.indexOf(guess.charAt(i)) != -1) {
                hint.append("+"); // Correct letter but in wrong position
            } else {
                hint.append("*"); // Incorrect letter
            }
        }
        return hint.toString();
    }
    public static void main(String[] args){
   // test data
        HiddenWord harps = new HiddenWord("HARPS");

        System.out.println(harps.getHint("HEART"));
        System.out.println(harps.getHint("HELLO"));
        System.out.println(harps.getHint("HARPS"));
    }

}
HiddenWord.main(null);

H*++*
H****
HARPS
