## Overview

This is a small Java library example: the main method creates two composed Book objects and prints their details. Book delegates detail access to Title, Author, Availability, and Price. Library.java contains a separate add/list/issue/return implementation, but it uses a different package and Book API than the sampled library package; its integration with the sample workflow is therefore uncertain. The README documents only the composition-and-display example.

Main entry points: [`LibraryManagementSystem.java`](https://github.com/pramodkumar524/libray-sys-mgt/blob/main/LibraryManagementSystem.java) (Main program), [`Book.java`](https://github.com/pramodkumar524/libray-sys-mgt/blob/main/Book.java) (Book), [`Title.java`](https://github.com/pramodkumar524/libray-sys-mgt/blob/main/Title.java) (Title), [`Author.java`](https://github.com/pramodkumar524/libray-sys-mgt/blob/main/Author.java) (Author)
