JAVA Trivia Game Array范围之外

标签: java arrays arraylist

我知道问题在于编译器说在代码中实际播放游戏的qArray部分存在错误,其中有评论说玩游戏。我认为qArray的范围超出了使用它的循环但我不确定如何将数据从intQuestions方法提升到需要的地方妨碍我使用它。或者我应该将问题数组放在qArray是@?

的位置

所需的输出是调用intQuestions方法然后将数据传递到for循环中使用的数组中,其中注释表示玩游戏!我理解qArray的范围在外,但我如何将数据从数组传递到它所说的游戏以及我使用它的方式?

 public class TriviaGame {

   public static void main(String args[]) throws IOException
   {

     // Constants
     final int NUM_QUESTIONS = 10;
     final int NUM_PLAYERS = 2;


     // Variables
     int playerTurn = 1; // The current player
     int questionNum; // The current question number
     int playerAnswer; // The player's chosen answer
     int player1points = 0; // Player 1's points
     int player2points = 0; // Player 2's points


     // Create an array of Player objects for player #1 and player #2.
     Player[] players = new Player[NUM_PLAYERS];

     for (int i = 0; i < NUM_PLAYERS; i++)

     {

        players[i] = new Player(i+1);

     }


     // Create an array to hold Question objects.
     Question[] questions = new Question [NUM_QUESTIONS];


     // Initialize the array with data.
     intQuestions(questions);


     // Play the game.
     for (int i = 0; i < NUM_QUESTIONS; i++)

     {
        // Display the question.
        TriviaGame.displayQuestion(qArray[i], playerTurn);


        // Get the player's answer.
        players[playerTurn - 1].chooseAnswer();


        // See if the correct answer was chosen.
        if (qArray[i].getCorrectAnswerNumber() == players[playerTurn - 1].getCurrentAnswer())

        {

            players[playerTurn -1].incrementPoints();

        }


        // See if the the player chose the wrong answer.
        // do nothing
        // Switch players for the next iteration.

        if (playerTurn == 1)

            playerTurn = 2;

        else

            playerTurn = 1;

     }

     // Show the game results.
     showGameResults(players);
 }

 /**

 * The intQuestions method uses the contents of the trivia.txt file to

 * populate the qArray parameter with Question objects.

 public static void intQuestions(Question qArray[]) throws IOException
 {

   // Open the trivia.txt file.

   File file = new File("trivia.txt");

   Scanner inputFile = new Scanner(file);


   // Populate the qArray with data from the file.
   for (int i = 0; i < qArray.length; i++)

   {

     // Create a Question object in the array.
     qArray[i] = new Question();


     // Get the question text from the file.
    qArray[i].setQuestion(inputFile.nextLine());


    // Get the possible answers.
    for (int j = 1; j <= 4; j++)

    {

       qArray[i].setPossibleAnswer(inputFile.nextLine(), j);

    }

    // Get the correct answer.
    qArray[i].setCorrectAnswerNumber(Integer.parseInt(inputFile.nextLine()));

 }
