java源代碼hangman

Question

我在java class中遇到了我的hangman程序有問題我似乎沒有得到丟失的生命計數器正常工作，並且顯示正確的已經猜到的字母不會在序列中顯示你做出下一個正確的猜測。

import java.util.Scanner; //imports scanner so I could use user input 
import java.util.Random; // imports random picker for words, to pick a random word 
public class javaxx { 
public static void main(String[] args) { 
    Scanner myScanner = new Scanner(System.in); 
    StringBuffer sb = new StringBuffer(); 
    StringBuffer buffer = new StringBuffer(); 
    String wordToGuess; 
    int wordLength; 
    int wordToGuessLength; 
    int position; 
    int livesLost = 0; 
    int totalLives = 7; 
    int lettersRemaining; 
    boolean guessInWord; 
    char guess; 
    StringBuffer prevGuessedLetters; 

    //declare variable 
    //String wordToGuess[] = new String[29]; 
    //insert array for words and their values 

    String[] myStringArray = new String[]{"programming","exhaustive","violin","selection","repetition","serendipity","watermelon","football","mobilephone","handbag","teddybear","cardigan","waterfall","cupcake","pineapple","strawberry","collection","chicken","tablecloth","candlestick","notebook","radiator","champagne","wineyard","parent","circus","snowbell","clocktower","mermaid","cardigan"}; 


    //Display the rules of the game 
     System.out.println("You are playing the game Hang Man. You have to guess the letters in the word. You will see how many letters are in the word and you have 7 changes to be wrong. "); 

     //choose a random word from the array 
     wordToGuess = myStringArray[(int) (Math.random() * myStringArray.length)]; 

     //determine the length of the word 
     wordLength = wordToGuess.length(); 

     //show the player how many letters are in the word 
     System.out.println("The word you are quessing has " + wordLength + " letters in it"); 
     lettersRemaining = wordLength; 

     for (position = 0; position < wordLength; position++) { 
       sb.append("_ "); 
     } 

    System.out.println(sb.toString()); 

    //loop starts 
    while (lettersRemaining > 0 && livesLost < 7) { 
     //prompt user to guess a letter 
     System.out.println("Guess a letter:"); 
     guess = myScanner.findWithinHorizon(".", 0).charAt(0); 

     //check if the letter guessed is in the secretWord 
     guessInWord = (wordToGuess.indexOf(guess)) != -1; 

     if (guessInWord == false) { 
      livesLost++; 
      System.out.print("Sorry, you have lost a life. You still have "); 
      System.out.print(totalLives -= livesLost); 
      System.out.println(" life/lives left. Keep trying."); 
     } else { 
      System.out.println("That was a good guess, well done!"); 

      for (position = 0; position < wordLength; position++) { 
       if (wordToGuess.charAt(position) == guess) { 
        System.out.print(guess); 
        lettersRemaining--; 
       } else { 
        System.out.print("_ "); 
       } 
      } 
     } 
     System.out.println(); 
     prevGuessedLetters = buffer.append(guess); 
     System.out.print("Previously guessed letters: "); 
     System.out.println(prevGuessedLetters); 
     System.out.print("Letters remaining: "); 
     System.out.println(lettersRemaining); 
    } 

    if (livesLost == totalLives) { 
     System.out.println("Sorry, you lose!"); 
    } else { 
     System.out.print("Well done, you win! The word was "); 
     System.out.println(wordToGuess); 
    } 
} 
} 

Answer 1

改變這一行

System.out.print(totalLives -= livesLost); 

到

System.out.print(totalLives - livesLost); 

這是與liveslost計數器的問題。
