Java, recursively reverse an array

Question

I haven\'t found anything with the specific needs of my function to do this, yes, it is for homework.

So I have:

public void reverseArray(int[] x) {
         


        

Answer 1

public class RecursiveArray {


   public static int[] backWardArray(int[] arr, int start, int end) {

       if (start < end) {
           int temp = arr[start];
           arr[start] = arr[end];
           arr[end] = temp;
           backWardArray(arr, start + 1, end - 1);
       }
       return arr;
   }

    public static void main(String[] args) {
        int [] arr = {12,4,6,8,9,2,1,0};
    int [] reversedArray= backWardArray(arr, 0, arr.length-1);
    //loop through the reversed array
        for (int i: reversedArray) {
            System.out.println(i);
        }
    }

    public RecursiveArray() {
    }
}
