Hangman Game Finding Duplicates

Question

到目前为止，我已经找到了单个字符，它甚至完成了大量的猜测，并向您显示猜测的单词。但我不能让它找到重复:(任何想法的家伙。 这是我的代码。

import java.util.*;

public class Hangman
{
    public static void main (String[] args)
    {
    String tempGuess;
    char blank = '_';
    int amountOfGuesses = 0;


    Scanner k = new Scanner(System.in);
    System.out.print("Please Enter A Word : ");
    String guessWord = k.nextLine();
    char[] myArray = guessWord.toCharArray();
    for (int i = 0; i < guessWord.length(); i++)
    {
    myArray[i] = blank;
    }
    System.out.println(myArray);
    boolean whilerun = true;
    while (whilerun == true)
    {
        System.out.print("Please Guess A Letter : ");
        String guessLetter = k.nextLine();
        amountOfGuesses = amountOfGuesses + 1;
        int tempLG = guessWord.indexOf(guessLetter);

        if (tempLG == -1)
        {
            System.out.println("Character Not In  Word");
        }   
        else
        {


        myArray[tempLG] = guessWord.charAt(tempLG);

        }

       System.out.println(myArray);
       String tempGW = new String(myArray);
       if (tempGW.equalsIgnoreCase(guessWord))
       {
           whilerun = false;
       }

    }
    System.out.print("Well Done You Guessed The Word In " + amountOfGuesses + " trys.");

    }
}

谢谢你们。

Answer 1

如果您希望代码在重复的条目上通知您，请将您的else语句更改为以下内容。

 else {
      String val = String.valueOf(myArray);
      if(val.contains(guessLetter)) {
          System.out.println("Char already found");
      }
      myArray[tempLG] = guessWord.charAt(tempLG);
}
