package com.bethecoder.tutorials.commons_lang.tests.arrays;

import org.apache.commons.lang3.ArrayUtils;

public class AddTest {

  /**
   @param args
   */
  public static void main(String[] args) {

    int [] ints = 123};
    int [] ints2 = new int[4];
    int [] ints3 = 8};
    
    ints = ArrayUtils.add(ints, 2999)//(array, index, element)
    System.out.println(ArrayUtils.toString(ints));
    
    ints2 = ArrayUtils.add(ints2, 0444)//(array, index, element)
    ints2 = ArrayUtils.add(ints2, 888)//(array, element)
    System.out.println(ArrayUtils.toString(ints2));
    
    int [] ints4 = ArrayUtils.add(ints3, 2666)//(array, index, element)
    System.out.println(ArrayUtils.toString(ints4));
  }

}
   

It gives the following output,
{1,2,999,3,4}
{444,0,0,0,0,888}
{8,9,666}
