Create a Java interface named IValidateUserStrategy. It should have a single method definition, validateUser.

Create $3$ implementations of this interface in the same package:

StrictValidateUserStrategy insists on passwords that are at least length $6,$ uses only letters, numbers, or the special

characters $!\_=$@$\%,$ and requires at least $1$ uppercase letter, $1$ lowercase letter, $1$ special character, and $1$ numeric digit.

ModerateValidateUserStrategy insists on passwords that are at least length $3,$ uses only letters or numbers, and

requires at least $1$ letter and $1$ numeric digit.

NullValidateUserStrategy insists on usernames and passwords that are not empty. Currently, when adding a new user,

you may add one that has no username or password $($leave the fields empty$).$

You will find that you can login as an admin by entering no credentials. This strategy allows any non$-$empty username and non$-$empty password comprised of only letters and numbers of any length.

Use your new strategy to check login attempts in your main class.
