Hi Friend,

You can try the following code:

import java.util.*;

public class InitialName {
        public static void main(String[] args) {
         Scanner input=new Scanner(System.in);
         System.out.println("Enter Name");
         String name=input.nextLine();
         input.close();
         int index = name.lastIndexOf( " " ) + 1;
         String st= name.substring(0,index);
         Scanner scan=new Scanner(st);
         while(scan.hasNext()){
         System.out.print(scan.next().charAt(0)+".");
         }
         scan.close();
         System.out.print(name.substring(index));
        }
}

Thanks
