A console app in Java manages a library's books, users and loans. It needs no database: it saves records to files with Java serialization.
- Manage books. Add, delete and search books, and update stock.
- Register users.
- Issue and return books. Stock goes down on issue and back up on return.
- List all books with author, ID, price and quantity.
Records are kept in ArrayLists while the app runs.
They are written to three files and read back on the next start:
| File | Holds |
|---|---|
books.ser |
Books |
users.ser |
Users |
issued_books.ser |
Issued books |
