KanwalLadhani/Library-System — reverse-engineered prompt

Build me a simple Java library system that someone can run locally and use from a clear menu.

I want it to let a librarian keep track of books and members, add new books, add new members, see what books are available, search by title or author, borrow a book, return a book, and show which member has which book checked out. Please save the data in plain text files like books.txt and members.txt so the information is still there after closing the program.

Keep it beginner friendly and easy to understand. Use simple classes for books, members, and the main library actions. Make the menu hard to break, with helpful messages if the user types something wrong or tries to borrow a book that does not exist. If anything is unclear, choose the simplest working version rather than making it fancy.
