You are to design a Java application program with files and classes and objects to manage books in a library and offer the following basic services:
Search for books
Check out books
Return books
Each book has the following data:
Title
ID
Category
Author
Publisher
Year published
Number of copies available
Books data of at least 20 books are saved in a text file and input into an array in the program. Updates of books data in the array are also saved back to the file. The user does not need to log in to use the services at the library and there is no need to keep users data. Design a password for the library manager to log in so he may add,delete and update books.
The user may use any of the following to search for books:
Title
Author
ID
Publisher
And, the user can check out any number of available books. Book check-outs and returns are "self service" and the user can use the book ID to identify each book.
The program must include at least the two classes below:
Book
Library
The Book class must include at least the methods below:
All the "get" and "set" methods for each data member
Constructors
"equals"
"toString"
The Library class must include at least the methods below:
