Java Project

This is a simple Java Swing program that I need to have revised as stated below by Saturday 07/24/10. Objective: The objective of this project is to refactor the previous code by making the Library persistent and use a HashMap to store the Book collection. Specification: Change the previous project by adding two new features: storing and retrieving the Library object in/from a file. The Library class should use a HashMap to store the Book objects. No major changes are neccesary in the design. Changes in GUI: Add two buttons: Save and Load to trigger the storing and retrieving of the Library object. Deliverables: Submit in the Assignments folder under the Project3 link the source files of your project (.java files). See the attached zip folder with the 6 Java classes. Let me know if you need any more clarification. THANKS!!!
