How to delete elements from Array in java

Array is collection of homogenous fixed size number of elements.If we want to create array object in our program, we should know the size of the array.It is a big problem to the programmers and clients.And once we create an array, cannot change its size and cannot delete elements from array.If you want to delete any element from array,you should create one more array and copy that array elements to this array except which elements you want to delete by using for loop. In java array is object but we donot have method like add,delete thats why collections are introduced in 1.2 version. To reducing burden of developers Apache giving one jar(Download) file. By using this array we can add or delete elements from array.See below snippet

package com.rrv;

import org.apache.commons.lang.ArrayUtils;

 public class ArrayElementDelete

{

   public static void main(String[] args){

      //create array object

     int[] naturalNumber = {1,2,3,6,4,7,6,8,9};

     System.out.println (" Array elements:  "+Arrays.toString(naturalNumber));

     

     //now you can delete element from array

    naturalNumbe = ArrayUitls.remove(naturalNumbers,5); //deleting index 5

   

     // After deleting element from array print the array elements

     System.out.println (" Array elements:  "+Arrays.toString(naturalNumber));

  }

}

Output:

Array elements: 1 2 3 6 4 7 6 8 9

Array elements: 1 2 3 6 4 6 8 9
