Question

我正在尝试获取阵列的特定输出。数组被放入while循环中以继续设置新数组，直到它到达计数器。计数器和每个数组中的元素数量排成一行，但是一旦我尝试获取输出，它就无法解决。我该怎么办才能解决这个问题？

public static void main(String[] args) {

    Scanner input = new Scanner(System.in);
    int i;  int j;  int n;  int u;

    int count = 0;

    n = input.nextInt();

    System.out.println("Times repeated: " + n);


    while(count < n) //counter represents amount of times loop will occur
    {
        i = input.nextInt();
        int[] numbers = new int[i];
        System.out.println("Length of Array: " + i);//represents how many numbers within a line
        count++;

        for(j = 0; j < numbers.length; j++) //numbers within line
        {
            numbers[j] = input.nextInt();}
            for(int p = 0; p < numbers.length - 1; p++) //prints specific values in line

            {


            numbers[p] = numbers[numbers.length - 1 ];
            p = numbers[p];
            System.out.println(p);
            System.out.println(Arrays.toString(numbers)); }

    input.close();}
 }  }

第一个用户输入：

3

2

10

1

预期产出： 10

相反，我得到1.我想要做的是从数组的其余部分中减去数组的最后一个元素以获得所需的输出。这也包括最后一个元素。

代码工作正常，只需要close scanner outside while.修复括号。

在循环中

input.close();

public static void main(String[] args) {

        Scanner input = new Scanner(System.in);
        int i;
        int j;
        int n;
        int u;

        int count = 0;

        n = input.nextInt();

        System.out.println("Times repeated: " + n);

        while (count < n) // counter represents amount of times loop will occur
        {
            i = input.nextInt();
            int[] numbers = new int[i];
            System.out.println("Length of Array: " + i);// represents how many numbers within a line
            count++;

            for (j = 0 ; j < numbers.length ; j++) // numbers within line
            {
                numbers[j] = input.nextInt();
            }
            for (int p = 0 ; p < numbers.length - 1 ; p++) // prints specific values in line

            {

                numbers[p] = numbers[numbers.length - 1];
                p = numbers[p];
                System.out.println(p);
                System.out.println(Arrays.toString(numbers));
            }

        }

        input.close();
    }
