Reverse arrays using Stacks in java

Problem:

Create a java program that reverses an array in java using stacks.

Output:

90 78 40 9 6 3 1
10.5 6.9 3.2 2.5

Solution:

import java.util.Stack;

public class ReverseArrayApp {

 public static void main(String[] args){
  Integer[] arr1 = {1, 3, 6, 9, 40, 78, 90};
  Double[] arr2 = {2.5, 3.2, 6.9, 10.5};
  
 
  Number[] arr1_rev = reverse(arr1);
  Number[] arr2_rev = reverse(arr2);
  
  
  for(Number eltInt : arr1_rev) 
   System.out.print(eltInt + " ");
  System.out.println();
  for(Number eltDouble : arr2_rev)
   System.out.print(eltDouble + " ");
  }

 
 private static Number[] reverse(Number[] arr) {
  Stack<Number> temp = new Stack<>();
  Number [] output = new Number[arr.length];
  
  for(Number elt: arr) 
   temp.push(elt);
  
  int index = 0;
  
  while(!temp.empty()){
   output[index] = temp.pop();
   index++;
  }
  
  return output;
  
 }
 
 
 }
