Here is the Code of the Example :

Get.java:

import java.util.*;
public class Get{
  public static void main(String argv[]){
  List v = new ArrayList ();
  v.addAll(Arrays.asList(new Integer[]{1,2,3,4}));
 
 
//cast the int value to an Integer object 

   Integer iw =(Integer)v.get(2);
  System.out.println(iw);
  }
}
