我知道问题是编译器说在代码中实际玩游戏的地方的qArray部分有错误，有一条注释说玩游戏。我认为是qArray的范围超出了使用它的循环范围，但是我不确定如何从intQuestions方法获取数据，直到达到使用方式为止。还是我应该将问题数组放在qArray是@的位置？
所需的输出是先调用intQuestions方法，然后将数据传递到for循环中使用的数组中，在该循环中，注释说要玩游戏！我知道qArray的范围在外面，但是如何将数据从数组传递到它说的可以玩游戏的地方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);
}

最佳答案
您可能应该在questions方法中使用qArray而不是main()：qArray仅在intQuestions()方法内部可见。当使用参数intQuestions()调用questions方法时，会将数组传递给该方法并对其进行一些初始化。方法intQuestions()完成后，将使用一些值初始化questions数组。
