B04 - User of the Library

After we created a Library and Book class we want to create a user to use this library.^{1 2}

Step 1

Create the following classes:

• Library in the solution folder
• Book in the “Media” folder
• UserAccount in the “User” folder

Step 2

Fill the UserAccount class with the following members:

• two string properties: “Name” and “EMail”
• a long property “ID”
  • all of them have a get and a private set
• a private array of Book as field “borrowedBooks”
  • the user can only borrow 5 books at a time
• a constructor with three parameters: name, email and id

Add to the Library class the following members:

• a private array field of UserAccount “users”
  • the library can only have 100 users at a time
• a private int field “userCount” that contains the number users already registered
• method RegisterUser with two parameters: name and email

Add to the Book class the following member:

• a private UserAccount field “borrowedTo”

Step 3

Implement the “Register” method. It should add a new user to the array of users. Create a new user with the given parameters.

Hint: We don’t get the id as parameter in this method. What can you use as an id for the constructor?

Step 4

Write for all created classes, methodes, properties and fields documentation comments.
