Action listener methods

To provide that a user can add, edit or delete a book, we have to include the appropriate functionality. This functionality will be implemented in action listener methods / classes. If an event occur (ex.: a user clicks on a link) an action listener method / class will be called and processed.

Open the class Book and add four methods , which process the following functionality.

• Initializise a book

• Edit a book

• Save a book

• Delete a book

Initialize a book
