May you fix what's wrong with this Java code?

The instructions for it:

Write a program that prompts the user for a domain name (e.g. google). The program should then concatenate that name with www. and .com to form a proper Internet domain name (e.g. www.google.com).

Your code should include comments to describe the program logic and use proper indentation for readability.

Be sure to properly test your code using both valid and invalid inputs. Make sure it compiles right, please.

The wrong code:

import java.util.Scanner; public class URLFromDomain { public static void main(String[] args) { Scanner in = new Scanner(System.in); System.out.print("Enter domain name: "); Il ask for domain name String domain = in.nextLine(); // read domain name from user String url = "www." + domain + ".com"; // form an url System.out.println(url); // print the URL } }
