Your task for this lab is to write and test a subclass of User called SecureUser. This subclass should override

the authenticate method to meet more stringent requirements. In particular, a SecureUser class should

"lock" a user out after three consecutive failed authentications. In other words, the authentication method

should return true only if the string passed into the method matches the password AND there have not been

three consecutive failed authentications. If the user has two failed authentications and then a successful

authentication, you should reset the number of consecutive failed authentications to zero. You should also

add code to Main.java so that it thoroughly tests the SecureUser class. It is up to you how many tests you

want to create.

You should not make any changes to User.java, and you should only add to Main.java. Do not change any

code that is already present.

Hint: You will probably find it useful to add a new field to the SecureUser class to keep track of the number

of consecutive failed authentications.
