Main 不会调用数组

Question

我制作了一个数组来随机选择“牛排、比萨饼或薯条”，但在运行我的程序时，它在你回答问题之前就出错了。在给我一个例外之前，它适用于大约 5 个输入。

我认为问题出在

{System.out.println(FoodArray.getRandomWord(args));

但我似乎无法弄清楚它有什么问题。

我只需要我的程序能够正确运行，当它遇到关于给出随机建议的问题时，它随机打印出牛排、比萨饼或薯条。

public static void main(String[] args) {

    int input = 0;

    int sweet = 0;

    int savory = 0;

    int salty = 0;

    Random r = new Random();

    FoodArray a = new FoodArray();

    Scanner myscanner = new Scanner(System.in);

    System.out.println("Welcome, lets figure out what you're hungry for."

            + "Press 0 to continue");

    input = myscanner.nextInt();

    if (input > 0) {

    }

    {

        System.out.println("What sounds the best to you right now?\n"

                + "1) Something sweet\n"

                + "2) Savory\n "

                + "3) Salty\n ");

    }

    input = myscanner.nextInt();

    if (input == 1) {

        System.out.println("something sweet. okay. next question");

        sweet++;

    } else if (input == 2) {

        System.out.println("Savory eh? got it. lets move on.");

        salty++;

    } else if (input == 3) {

        System.out.println("Sounds good. Lets proceed");

        savory++;

    }

    System.out.println("Press 0 to continue");

    input = myscanner.nextInt();

    System.out.println("pick a number 1-3");

    input = myscanner.nextInt();

    if (input == 1) {

        System.out.println("Very interesting.");

        sweet++;

    } else if (input == 2) {

        System.out.println("Very interesting.");

        salty++;

    } else if (input == 3) {

        System.out.println("Very interesting.");

        savory++;

    }

    System.out.println("Press 0 to continue");

    input = myscanner.nextInt();

    System.out.println("Next question: "

            + "Would you rather, fly, (1) breath underwater, (2) or be invisible (3)");

    input = myscanner.nextInt();

    if (input == 1) {

        System.out.println("Good choice.");

        sweet++;

    }

    if (input == 2) {

        System.out.println("Would be pretty cool");

        salty++;

    }

改成::食品阵列::String[] strArray = { "Pizza", "Steak", "Chips" };至public static String[] strArray = { "Pizza", "Steak", "Chips" };：：主要的：：FoodArray.getRandomWord(args)至FoodArray.getRandomWord(FoodArray.strArray)但这是愚蠢的，因为FoodArray已经知道strArray所以删除参数传递给这个方法并strArray在其中使用FoodArray
