As part of this assignment, students are requested to use at least one design pattern from each section learnt from this course.

Library Management Software is "Menu driver" program which can use standard input and output (terminal) to operate.

* Inventory management of books. ( listing / add / remove books in library )

* Crud operation for members of library. (add/remove/edit members)

* Assign books to library member.

* Validation - Do not allow duplicate assignment.

* Fine calculator for late submissions of books.

* Wish list of books for a member.

Design classes and objects keeping different design patterns in mind:

* Creational design pattern to create and add objects (books/members) in system.

* Structural design pattern to establish relationship between objects and classes

Eg. Proxy books to save loading time

* Behavioral while establishing communication between components

Eg. Observer for wish list component.

* Write Dry code ( Do not repeat yourself - have reusable components)

* Write Loosely coupled and cohesive classes

* Please Program against interface.

Use database of your choice but try to avoid DB dependency and use Java collections with some seed data (call in init block).

* Please raise the pull request in https://github.com/premaseem/DesignPatternsJava9 as a separate branch from your fork.

* Feel free to discuss your idea in Software Design pattern community page https://www.facebook.com/DesignPatternGuru
