B02 - Book and Library

This time we want to create three classes and fill them with some code.^{1 2}

Step 1

Create the following classes:

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

Step 2

Fill the Book class with the following members:

• three string properties: “Title”, “Autor” and “ISBN”
  • they have a get and a private set
• a constructor with three parameters: title, autor and isbn
• a method “Search” that searches in its members with a given search query and returns true if a member match with the query

Fill the Library class with the following members:

• a private array field of Book “books”
  • the library can only manage 500 books at a time
• a private int field “bookCount” that contains the number of books already in the stock
• a standard constructor
• a method “Search” that serches through all books with a given search query and returns an array of Book
• a method “AddNewBook” that adds a given book (as parameter) to the stock of all books of the library

Step 3

Implement (if you haven’t done it yet) the “Search” method in Book.

Step 4

Now we want to implement the “Search” method in Library. This method should only search if the search query has a length greater than 2. The result array should have the size³ of the numbers of results and not more.

Hint: Maybe you need a temporary array to solve this.

Step 5

Finally we implement the “AddNewBook” method. It should add the new book to the stock of books and save the new book count.
