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

//We are just doing an operation here and calling a helper method.

public void reverseArray(int[] nums){
  int[] hold = new int[nums.length]; //just so it will take this argument
  int[] reversed = recurReverseArray(nums, hold, nums.length - 1, 0);
  nums = reversed; //not returning just changing nums to be reversed.
}
public int[] recurReverseArray(int[] nums, int[] reverse, int end, int start){
  if(end == 0 && start == nums.length - 1){
  reverse[start] = nums[end];
  return reverse; //the way out.
  }
  reverse[start] = nums[end];
  return recurReverseArray(nums, reverse, end - 1, start + 1);
}
