Username Generator using Java

This code is used to generate a username based on the user's first name, last name, and phone number. The code first takes the first two letters of the user's last name and stores it in a variable called ln. It then takes the user's phone number and calculates the sum of the squares of the digits in the phone number and stores it in a variable called phn. It then takes the first two digits of the phn variable and stores it in a variable called ph. It then takes the user's first name and replaces all the 'a' characters with 'x' and stores it in a variable called fn. Finally, it combines the fn, ln, and ph variables and stores it in a variable called username. It then prints out the username.
