Password Keeper

Create a JavaFX program that helps the user keep track of their passwords.

There must be a screen to login - with a username(ID) and a password

If the user doesnt have a username and password, there must be a screen to create a new one.

Passwords must be between 8 and 10 alphanumeric characters, have at least 1 capital

letter, 1 number, and one special character NOT a space

Usernames must be checked against existing usernames - if a username that already

exists is chosen on registration, you must give an appropriate error message and allow

the user to pick a new user name

This project should have:

An Abstract Password class with a print mechanism for passwords and an interface for validating passwords

A simple password class that allows for unvalidated passwords

A complex password class that has a validation method that throws an exception
