Hi Friend,

Try the following code:

import java.util.*;
class CollectionExample
{
    public static void main(String[] args) 
    {
        ArrayList list=new ArrayList();
        Scanner  input=new Scanner(System.in);
        System.out.println("Enter List Elements: ");
        for(int i=0;i<5;i++){
            String st=input.next();
            list.add(st);
        }
        System.out.println();
        System.out.println("List Elements are: ");
        for(int i=0;i<list.size();i++){
            System.out.println(list.get(i));
        }
        System.out.println();
        System.out.println("Enter the index of element to remove: ");
        int index=input.nextInt();
        list.remove(index);
        System.out.println();
        System.out.println("Now the list is: ");
        for(int i=0;i<list.size();i++){
            System.out.println(list.get(i));
        }
        System.out.println();
        System.out.println("Enter the index of new element to add: ");
        int in=input.nextInt();
        list.add(in,"RoseIndia");
        System.out.println();
        System.out.println("Now the list is: ");
        for(int i=0;i<list.size();i++){
            System.out.println(list.get(i));
        }
    }
}
