Here is the question and below it is the file that will be modified according to the question. Please solve it clearly so that I can apply the same steps and get the result

You will create a password verification program using character testing. Start with the program CustomerNumber.java( The file is at the end of this file under the question, and I put a yellow highlight on the file that you will work on) Naming: . Name the Java project: LastFProjectAssign07 . Name the driver program (main): LastFAssign07.java . Where Last is your last name and F is the first initial of your first name. Ex: AladmyR . Save in a file folder on your storage device. Instructions: The user will enter a password as a String. You must test that the password contains at least: . The password should be at least 8 characters long. . One lowercase letter . One uppercase letter . One number (0-9} . Must contain a $. . The password can contain no spaces Hint: you will need a loop and one or more boolean flags. Tell the user what they entered incorrectly. Your output does not need to be exactly like mine. Sample output 1: Enter a password: Invalid Length. Password must contain at least one upper, one lower, and one digit. That is not the proper format. Sample output 2: Enter a password: Password may not contain spaces. That is not the proper format. Sample output 3: Enter a password: Password must contain a \"\".$ That is not the proper format. SampleoutDUt 4; Enter a password: That's a valid password. Test the program and make sure it runs. I want to see comments and descriptive variable names throughout your program!!!!
