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 and a password

If the user doesn’t 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

Once logged in, the user has three options:

Add a new site, login, and password, and notes

List all logins, passwords, and notes

Search for a login based on a site

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

A Site class that includes website, username, password, and notes

The Site class should validate the website URL and throw an exception if invalid

A method to save usernames and passwords for the Password Keeper, and a method to

save Site class data (all as text).

This project covers the following SLOs:

Objects & Classes

Arrays

Inheritance

Polymorphism

JavaFX

Exception Handling

Text I/O

Abstract classes

Interfaces
