Many documents use a specific format for a person's name. Write a program whose input is: firstName middleName lastName and whose output is: lastName, firstInitial. middleInitial. Ex: If the input is: Pat Silly Doe the output is: Doe, P. S. If the input has the form: firstName lastName the output is.

The solution code is written in Python:

Explanation:

Firstly, prompt user to enter name (Line 1).

Next, use the string split() method and use space " " as separator to split the input string into individual component, first name, middle name, last name and assign to variable first_name, middle_name and last_name (Line 5-7).

Display the output as required by the question.

The code is given below in Java with appropriate comments

Explanation:

//declaring the imports

import java.util.Scanner;

//class FormatName

public class FormatName {

    public static void main(String[] args) {

        Scanner scanner = new Scanner(System.in);

       //inputing the names

       System.out.print("Enter your name (first middle last): ");

       String fullName = scanner.nextLine();

       String[] names = fullName.split("\\s+");

//applying the formatting

       if (names.length == 2) {

           System.out.println("Formatted Name: " + names[1] + ", " + names[0]);

       } else if (names.length == 3) {

           System.out.println("Formatted Name: " + names[2] + ", " + names[0] + " " + names[1].charAt(0) + ".");

       } else {

           System.out.println("The input does not have correct form");

       }

   }
