Java program to remove a specific element from an array. code example

Example: Remove element from a specific index from an array in java

// remove element from a specific index from an array
import java.util.Arrays;
public class DeleteElementDemo
{
   // remove element method 
   public static int[] removeElement(int[] arrGiven, int index) 
   {
      // if empty 
      if(arrGiven == null || index < 0 || index >= arrGiven.length) 
      {
         return arrGiven; 
      }
      // creating another array one less than initial array 
      int[] newArray = new int[arrGiven.length - 1];
      // copying elements except index 
      for(int a = 0, b = 0; a < arrGiven.length; a++) 
      { 
         if(a == index)
         {
            continue;
         }
         newArray[b++] = arrGiven[a]; 
      }
      return newArray; 
   }
   public static void main(String[] args) 
   { 
      int[] arrInput = { 2, 4, 6, 8, 10 };
      // printing given array 
      System.out.println("Given array: " + Arrays.toString(arrInput));
      // getting specified index 
      int index = 3;
      // print index 
      System.out.println("Index to be removed: " + index);
      // removing element 
      arrInput = removeElement(arrInput, index);
      // printing new array 
      System.out.println("New array: " + Arrays.toString(arrInput));
   }
