having a secure password is a very important practice, particularly when much of our personal information is stored online.

write a program that validates a new password, following these 4 rules:

the password must be at least 8 characters long.
the password must have at least one upper case letter.
the password must have at least one lower case letter.
the password must have at least one digit.
1) your program should ask for a password, and then check first to see if the password is valid (i. e., conforms to the specifications outlined above.) if not, the program should allow the user to continue to enter passwords until s/he enters a valid password.

2) then your program should confirm the password by requesting that the user enter the password again, and verify that the two match. if they don't match, allow the user to try it again (for a total of 3 tries only).

you will need a minimum of two methods, one to confirm the two passwords, and at least one (or more) to check to see if the password meets the 4 required specifications outlined above.

carefully examine and follow all the program requirements. make sure you use prologue comments for your program, including prologue comments for each of your methods. you will find both the java string methods as well as the character class methods immensely for this lab. use comments as well for any part of your code that may not be self-explanatory or may require some additional documentation.
