import java.util.ArrayList;


public class ArrayListExample {
    public static void main(String [] args){

     ArrayList<String> array = new ArrayList<String>();
       array.add("Amit");
       array.add("Ankit");
       array.add("Vinay");
       array.add("Deepak");
       array.add("Naulej");
       array.add("Arun"); 

    System.out.println("ArrayList Size:"+array.size());
       for(int i=0;i<array.size();i++){             
        System.out.println("ArrayList Element"+i+" :"+array.get(i));           

         }   
       }

     }

ArrayList Element0 :Amit
ArrayList Element1 :Ankit
ArrayList Element2 :Vinay
ArrayList Element3 :Deepak
