Collegeboard 2015 Practice Exam FRQ 2 • 3 min read

Classes

• This FRQ was about comparing and finding the similarities between a secret word and a guessed word. This FRQ is basically the extremely popular game Wordle and I’m surprised it became as popular as it did being this simple. For this question, I had to go through a guessed word and give clues based on matching letters and if they’re in the hidden word. This was very challenging for me and I had to google a few things (such as the charAt function) to make the program much a lot simpler. By using Classes, I managed to finish the Wordle game.

Program

public class HiddenWord {
    
    public String word;
    
    public HiddenWord(String w) {
        word = w;
    }

    public String getHint(String guess) {
        String result = "";

        for (int i = 0; i < guess.length(); i++) {
            if (guess.charAt(i) == word.charAt(i))
                result += "" + guess.charAt(i);
            else if (word.indexOf(guess.charAt(i)) > -1)
                result += "+";
            else
                result += "*";
        }

        return result;
    }

    public static void main(String[] args) {
        HiddenWord puzzle = new HiddenWord("HARPS");
        System.out.println(puzzle.getHint("AAAAA"));
        System.out.println(puzzle.getHint("HELLO"));
        System.out.println(puzzle.getHint("HEART"));
        System.out.println(puzzle.getHint("HARMS"));
        System.out.println(puzzle.getHint("HARPS"));
    }
}

HiddenWord.main(null);
