Write a complete program to generate a username based on a user's first and last name. Part One: Get a Valid First and Last Name ask the user for and read in their first and last nameuse a loop to validate the first name: it must be at least one character long and it must start with a letteruse a loop to validate the last name: it must not contain any spacesHint: use a nested loop. The outer loop will iterate until there is valid input. The inner loop will check each character in the String to see if any of them are whitespace.Part Two: Generate a Username generate a two-digit random number (i.e., a random number between 10 and 99, inclusive)create a username that is the following data concatenated:the first letter of their first name in lower casethe first five characters of their last name in lower case; if the name is shorter than five characters, use the whole last namethe two-digit numberoutput the username to the userAdditional Coding Requirements code should compileuse existing methods in the String and other classeschoose the best loop and conditional structure for the taskwrite your program in a way that reduces duplicated or repeated codefollow Java naming conventions for variables (lower camel case with no underscores)HintsUse the Character.isLetter(char) and Character.isWhitespace(char) methods.Write code to focus on a single task at a time.

Part One: Get a Valid First and Last Name

ask the user for and read in their first and last name
use a loop to validate the first name: it must be at least one character long and it must start with a letter
use a loop to validate the last name: it must not contain any spaces
- Hint: use a nested loop. The outer loop will iterate until there is valid input. The inner loop will check each character in the String to see if any of them are whitespace.

Part Two: Generate a Username

generate a two-digit random number (i.e., a random number between 10 and 99, inclusive)
create a username that is the following data concatenated:
- the first letter of their first name in lower case
- the first five characters of their last name in lower case; if the name is shorter than five characters, use the whole last name
- the two-digit number
output the username to the user

Additional Coding Requirements

code should compile
use existing methods in the String and other classes
choose the best loop and conditional structure for the task
write your program in a way that reduces duplicated or repeated code
follow Java naming conventions for variables (lower camel case with no underscores)

Hints

Use the Character.isLetter(char) and Character.isWhitespace(char) methods.
Write code to focus on a single task at a time. Test that code and make sure it is working before moving onto another task. Note that the "tasks" don't necessarily line up with the "parts" of the assignment. For example you might write and test code to work on each of this individually:
- ask for and read in the first name
- use a loop to validate the first name
- get the lowercase first character of the first name
- ask for and read in the last name
- use the loop (or nested loops!) to validate the last name
- get the first five characters of the last name, in lowercase
- generate the random number
- concatenate all the pieces together
