Question

我试图制作一个刽子手程序并且我没有错误，但程序将在我运行时终止。你看到我的代码有什么问题吗？我可以将StringBuilder添加到我的代码中更改的字符串吗？我还想创建一个驱动程序类，但不确定要放入什么。

package hangman;

import java.util.Random;


public class hangman
{
  public static void main1(String[] args){
  }




  //the word to be guessed

  private String word = null;

  // the array of possible words */
  private String[] wordArray = {"help","word","work","pant", "farm", "blue", "swim", "bike", "jump", "snow"};

  // the random number generator */
  private Random randNumGen = new Random();

  // the characters that were guessed that were wrong */
  private String wrongGuesses = "";

  // the characters that were guessed that were right */
  private char[] rightGuesses = {' ',' ',' ', ' '};



  // Randomly picks the word from the wordArray

  public hangman()
  {
    int index = randNumGen.nextInt(wordArray.length);
    word = wordArray[index];
  }





  public boolean guess()
  {
    boolean done = false;

    Object SimpleInput;
    // get input from user
    String guessStr = ("Enter a letter");

    // check if still have at least one letter
    if (guessStr.length() > 0)
    {
      // get first letter
      char guessChar = guessStr.charAt(0);

      // check this letter
      done = this.guess(guessChar);
    }
    return done;
  }

  //Method to guess a letter 

  public boolean guess(char guessChar)
  {
    int index = word.indexOf(guessChar);
    boolean done = false;

    // if the letter is in the word
    if (index >= 0)
    {


      // add letter to correctly guessed letters 
      rightGuesses[index] = guessChar;


      // check if the user won
      int numRightGuesses = 0;
    if (numRightGuesses == 4)
      {

        done = true;
      }
    }
    else
    {
      // add letter to string with wrong letters
      wrongGuesses = wrongGuesses + guessChar + " ";





      int numWrongGuesses = 0;
    // check if this was the last wrong guess
      if (numWrongGuesses == 6)
      {
        done = true;
      }
    }
    return done;
  }

  /**
   * Method to play the game till the user
   * wins or loses
   */
  public void playGame()
  {
    boolean done = false;
    // loop while we haven't reached the end of the game
    while (!(done = guess()))
    {}
  }




}

Answer 1

您的程序需要一个起始点。计算机需要知道程序的开始位置。

开头的public static void main(String[] args)方法在“主”之后落后于“1”，即一个点。另一点是你必须用main方法调用你的游戏。

public static void main(String[] args) {
    hangman game = new hangman();
    game.playGame();
}

Answer 2

您的main（）方法为空。这是您的应用程序的主要入口点，它没有做任何事情，所以程序干净利落。成功...？

Answer 3

使用以下代码替换main方法，它将创建类的对象，并且将执行构造函数内的代码

  public static void main(String[] args){
      hangman game = new hangman();
      game.PlayGame();
  }

我似乎无法让我的刽子手java程序工作
