A Method to Reserve a Book

A method in JADE is called an 'operation' in Rational Rose.

We will provide a borrower with a method that attempts to reserve a book.

The method takes the book as a parameter and returns true if the book was reserved, false otherwise.

Instructions

1. In the Browser, right-click the Book class and select
   New Operation from the popup menu.
2. Overtype reserve as the name for the operation.
3. Double-click the reserve operation. The Method Specification dialog is displayed.
4. On the Method tab, select Boolean as the Return Type.
5. On the Parameters tab, define a parameter named bk of type Book and click the Add button.
