Question

Assignment 2

Create a Java program called UserNames that reads the user's first and last name (separately), then prints a string composed of the first 4 letters of the user's last name, followed by the first letter of the user's first name, followed by a random number in the range of 10 to 99 (inclusive). You can assume the first name is at least one letter long and the last name is at least 4 letters. After doing this once, the program should ask the user if there is another user and then repeat if the answer is "y" or "Y". Otherwise, the program should end.

Additional Requirements
The name of your Java Class that contains the main method should be UserNames. All your code should be within the main method.
Your code should follow good coding practices, including good use of whitespace (indents and line breaks) and use of both inline and block comments.
You need to use meaningful identifier names that conform to standard Java naming conventions.

***The code in the below screenshot is neatly indented for better understanding.

import java.util.Random;
import java.util.Scanner;
public class UserNames
{
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        // repeat
        while (true)
        {
            // Prompt for first name
            System.out.print("\nEnter your first name: ");
            String firstName = scanner.next();

            // prompt for last name
            System.out.print("Enter your last name: ");
            String lastName = scanner.next();

            Random random = new Random();
            String output = lastName.substring(0, 4) + firstName.charAt(0) + ((10 + random.nextInt(100)) % 100);
            System.out.println("The Output is: " + output);

            // ask if the user wants to repeat
            System.out.print("Do you want to continue...(y/n): ");
            char choice=scanner.next().charAt(0);
            if(choice=='y' || choice=='Y')
                continue;
            else
            {
                // STOP here
                System.out.println("Good Bye..!");
                break;
            }
        }
    }
