java - 我希望将输入存储在数组中并在一行中打印该特定 int 的字符串

Question

我希望将整数存储在数组中，然后一旦用户输入 0，while 循环就会停止并以字符串格式打印数组的内容。

我尝试了该地区的一些事情，但老实说我不理解它们。

public static void apples() {
    Scanner input = new Scanner(System.in);

    System.out.println("Enter your integer: ");
    int number = input.nextInt();
    int[] array = {};

    while(number != 0) {
        if(number == 1){
            System.out.println("0");
        }
        else if (number == 3) {
            System.out.println("f");
        }
        else if (number == 5) {
            System.out.println("-l");
        }
        else if (number == 7) {
            System.out.println("V");
        }
        else if (number == 9) {
            System.out.println("-/");
        }
        else if (number == 11) {
            System.out.println("()");
        }
        else if (number == 13) {
            System.out.println("()");
        }
        else if (number == 15) {
            System.out.println("^");
        }
        else if (number == 17) {
            System.out.println("E");
        }
        else if (number == 19) {
            System.out.println("=");
        }
        else if (number == 21) {
            System.out.println("x");
        }
        else if (number == 23) {
            System.out.println("y");
        }
        System.out.println("int: " +  number);
    }
};

我的预期结果是输入 135输出为 0f-l

看一下这个使用 Map 和 List 的简单示例。

 public static void main(String[] args) {
        Map<Integer, String> map = new HashMap<>();
        map.put(0, "");
        map.put(1, "0");
        map.put(3, "f");
        map.put(5, "-1");
        map.put(7, "V");
        map.put(9, "-/");
        map.put(11, "()");
        map.put(13, "()");
        map.put(15, "^");
        map.put(17, "E");
        map.put(19, "=");
        map.put(21, "x");
        map.put(23, "y");
        List<Integer> listOfInputIntegers = new ArrayList<>();
        Scanner input = new Scanner(System.in);
        int integer;

        do {
            System.out.print("Input your next number:");
            integer = input.nextInt();
            listOfInputIntegers.add(integer);

        } while (integer != 0);
        for (int i : listOfInputIntegers) {
            System.out.print(map.get(i));
        }
        System.out.println();
    }
