Question

When a user signs in for the first time to a website, the user must submit personal information, such as last name, first name, email address, and so on. Typically, there are two fields for passwords, requiring the user to enter the password twice, to ensure that the user did not make a typo in the first password field.

Write a class encapsulating user with the following attributes:

UserID

Password

Reentered password

Email address

Last Name

First Name

Zip

You will store these values as strings.

Write the following methods in your class:

1. A constructor which will initialize the 7 attributes listed above.

2. Accessor, mutator, toString methods

3. A method returning the user id consisting of the first letter of the first name, last two letters of the last name and the first three nambers of the zip code and a random number (between 0 and 999)

4.. A method checking if the two Strings representing the password fields are the same, if they are return true, otherwise false.

Write a test class to create 2 user objects (using your constructor) and test all the methods in your class.

Remember to submit all your .java files, .class files and screenshots of your code and output and psuedocode
