Array reverse order

With this example we are going to demonstrate how to reverse the order of an array. We are using the org.apache.commons.lang3.ArrayUtils class, that provides operations on arrays, primitive arrays (like int[]) and primitive wrapper arrays (like Integer[]). In short, to reverse the order of an array you should:

  • Create a String array.
  • Use the toString(Object array) method of ArrayUtils to get the array as a String, treating null as an empty array.
  • Use the reverse(byte[] array) method to reverse the order of the given array.

Let’s take a look at the code snippet that follows:  

package com.javacodegeeks.snippets.core;

import org.apache.commons.lang3.ArrayUtils;
public class ArrayReverseOrder {
    public static void main(String[] args) {

    	String[] fruits = { "Orange", "Apple", "Blueberry", "Guava"

    , "Apple", "Peach", "Orange", "Strawberry" };
    	System.out.println("Before : " + ArrayUtils.toString(fruits));

  // Use reverse method to reverse the array 


  System.out.println("After :" + ArrayUtils.toString(fruits));


Before : {Orange,Apple,Blueberry,Guava,Apple,Peach,Orange,Strawberry}
After :{Strawberry,Orange,Peach,Apple,Guava,Blueberry,Apple,Orange}

This was an example of how to reverse the order of an array in Java.
