java - 絞首刑執行人プログラムで推測された文字を表示しますか?

Question

絞首刑執行人プログラムで推測された文字を表示できるようにしたいと考えています。たとえば、単語が hello の場合、プレーヤーには次のように表示されます。h はプレーヤーによって推測されますが、そのように「はい」と表示されますが、文字列 h *** が表示されます。これを達成する方法を知っている人はいますか? これが私のコードです：

ゲーム.java

    package hangman;

import java.util.ArrayList;
import java.util.List;
import java.util.Random;
import java.util.Scanner;

public class Game {
    String player = "";
    int turn = 12;
    List<String> wordBox = new ArrayList<String>();
    boolean hangman = false;
    Scanner scan;
    Random random = new Random();

    String letters;     // For displaying letters
    String mask;        // For character Mask

    public Game(String[] words, Scanner scanner){
        scan = scanner;

        int selectA = random.nextInt(words.length);

        letters = words[selectA];               //Load word into String for display. This just makes the code more readable.        
        mask = letters.replaceAll("\\S", "*");  // Mask the words

        System.out.println("Random String selected: " + mask);
        System.out.println("This word contains " + letters.length() + " letters");

        while (hangman == false) {
            System.out.println("Turns remaining: " + turn);
            System.out.println("Please choose a letter A-Z :");
            String ChosenLetter = scan.next();

            if (wordBox.contains(ChosenLetter)) {
                System.out.println("Letter already chosen please choose another letter");
            } else {
                wordBox.add(ChosenLetter);
            }

            if (letters.contains(ChosenLetter)) {
                char[] cLetters = letters.toCharArray();    //Load letters and mask to char array for editing
                char[] cMask = mask.toCharArray();

                for(int i=0; i < cMask.length; i++){
                    if(cLetters[i] == ChosenLetter.charAt(0)){
                        cMask[i] = cLetters[i];
                    }
                }

                mask = new String(cMask);   //Load new mask into String

                System.out.println("Wordbox letters are: " + wordBox);
                System.out.println("Yes!" + mask);                      // Prints mask after Yes!

                turn--;
            } else {
                System.out.println("Wordbox letters are: " + wordBox);
                System.out.println("No!" + mask);                               //Prints mask after No!
                turn--;
            }

            if (turn == 0) {
                hangman = true;
            }

            while (hangman == true) {
                System.out.println("You lose!");
                System.exit(0);
            }
        }
    }
}

次に、私があなたの質問にどのように答えたかを示したいと思います。

mask上記のコードでは、単語をandという名前の変数にロードしたことがわかりますletters。次に、このコードでこれらの変数を使用しました

 char[] cLetters = letters.toCharArray();//Load letters and mask to char array for editing
 char[] cMask = mask.toCharArray();

 for(int i=0; i < cMask.length; i++){
      if(cLetters[i] == ChosenLetter.charAt(0)){
          cMask[i] = cLetters[i];
      }
  }

  mask = new String(cMask); //Load new mask into String

  System.out.println("Wordbox letters are: " + wordBox);
  System.out.println("Yes!" + mask);                        // Prints mask after Yes!

いいえ System.out.println("No!" + mask);

これがお役に立てば幸いです。そして、コードの素晴らしい仕事。メニューを設定する方法が大好きです。

Answer 2

レベルごとにこれを行う必要があります。indexOf基本的に、単語内の文字の位置を見つけて置き換えることに依存しています。

            if (easyWords1[selectC].contains(hardChosenLetter)) {
                String word = easyWords1[selectC];
                char[] unMasked = replaceAllHard.toCharArray();
                unMasked[word.indexOf(hardChosenLetter)] = hardChosenLetter.charAt(0);
                replaceAllHard = new String(unMasked);
                System.out.println("Wordbox letters are: " + wordBox);
                System.out.print("Yes!");
                System.out.println(replaceAllHard);
                turn--;

            } else {
                System.out.println("Wordbox letters are: " + wordBox);
                System.out.println("No!");
                turn--;
            }
