Workshop 2w — Full Workshop Project

Neighborhood Library

Build a book checkout system with a menu-driven flow — this is the Week 2 workshop

What You're Building

Build a neighborhood library system where users can browse books, check them out, and return them. Create a Book class with five properties. Your inventory is an array of 20 or more books, all preloaded (no adding books at runtime). The home screen shows three options: Show Available Books, Show Checked Out Books, and Exit. When viewing available books, the user can select one to check out. When viewing checked out books, the user can select one to check back in.

Book Class Fields:

idUnique book identifier (int) isbnISBN number (String) titleBook title (String) isCheckedOutCurrently checked out? (boolean) checkedOutToName of borrower (String, empty if available)
This is a workshop project — it is larger than a regular exercise. It combines classes, arrays, loops, and menu logic into one complete application. Take it one screen at a time.
