顯示猜到的劊子手程序信？

Question

我希望能夠一旦在我的劊子手程序猜到顯示推測的信。因此，例如，如果這個詞是你好，它會顯示給玩家所以是h是玩家猜對了，它會說是，因爲它確實，但然後顯示字符串h ***沒有人知道我可以怎麼做做到這一點？這裏是我的代碼：

劊子手類：

Answer 1

首先，我想建議您分裂劊子手代碼爲兩個文件。防爆。

Hangman.java

package hangman; 

import java.util.Scanner; 

/** 
* 
* @author Adam2_000 
*/ 
public class Hangman { 

    /** 
    * @param args the command line arguments 
    */ 
    public static void main(String[] args) { 

     String selection; 
     Scanner scan = new Scanner(System.in); 

     /* 
     * I moved the variables found here to the Game class 
     */ 

     //New instances of class and arrays 
     Words words = new Words(); 


     System.out.println("Welcome to Hangman version 1"); 
     System.out.println("Please choose a difficulty"); 
     System.out.println("A: Easy"); 
     System.out.println("B: Medium"); 
     System.out.println("C: Hard"); 
     System.out.println("X: Exit");  // Just for user friendlyness 

     System.out.println(" _________  "); 
     System.out.println("|   | "); 
     System.out.println("|   0 "); 
     System.out.println("|  /|\\ "); 
     System.out.println("|  /\\ "); 
     System.out.println("|    "); 
     System.out.println("|    "); 

     char iChoice; 

     do { 
      selection = scan.nextLine().toUpperCase(); 
     } while (selection.isEmpty()); 

     iChoice = selection.charAt(0); 
     if (iChoice != 'X') { 
      switch (iChoice) { 
       case 'A': 
        System.out.println("You have chosen easy:"); 
        new Game(words.easyWords, scan);    //All three levels can be called from the same class with the same code. 
        break;           //This will help reduce amount of code, and help when you need to change all three at once. 

       case 'B': 
        System.out.println("You have chosen Medium"); 
        new Game(words.mediumWords, scan);    //Called with the String[] of words you want to use and the scanner to save memory. 
        break; 

       case 'C': 
        System.out.println("You have chosen Hard"); 
        new Game(words.hardWords, scan); 
        break; 
      } 
     } 
    } 
} 

Game.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); 
      } 
     } 
    } 
} 

接下來，我想告訴你我是如何回答你的問題。

在上面的代碼，你會看到，我已加載字到名爲mask和letters一些變量。然後我用這段代碼

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! 

和無 System.out.println("No!" + mask);

我希望這是有幫助的那些變量。與代碼很好的工作。我喜歡你如何設置菜單。

Answer 2

您將需要爲每個級別做到這一點。基本上，它依靠indexOf找字中的一個字符的位置和更換。

  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--; 
      }
