Solution

public static void main(String[] args) {
      Scanner scnr = new Scanner(System.in);       
      /* Type your code here. */
      String full_name = scnr.nextLine();
      String[] parts = full_name.split(" ");
      String first_name = parts[0];
      String last_name = parts[parts.length - 1];
      
      String final_name = last_name.substring(0,1) + "., " + first_name;
      
      if (parts.length >2){
         String middle = parts[1].substring(0,1);
         final_name += " " + middle + ".";
      }
      System.out.println(final_name);
   }
}
