How to remove element from Array in Java with Example

For this example you will need to download commons-lang-2.6.jar and set it in your classpath.

 import java.util.Arrays;  
 import org.apache.commons.lang.ArrayUtils;  
 /**  
  *

 public class RemoveObjectFromArray{  
   public static void main(String args[]) {  
     //let's create an array for demonstration purpose  
     int[] test = new int[] { 101, 102, 103, 104, 105};  
     System.out.println("Original Array : size : " + test.length );  
     System.out.println("Contents : " + Arrays.toString(test));  
     //let's remove or delete an element from Array using Apache Commons ArrayUtils  
     test = ArrayUtils.remove(test, 2); //removing element at index 2  
     //Size of array must be 1 less than original array after deleting an element  
     System.out.println("Size of array after removing an element : " + test.length);  
     System.out.println("Content of Array after removing an object : "  
               + Arrays.toString(test));  
   }   
 }  
 Output:  
 Original Array : size : 5  
 Contents : [101, 102, 103, 104, 105]  
 Size of array after removing an element : 4  
 Content of Array after removing an object : [101, 102, 104, 105]
