Developing a Zoo Management System in Java Programming Language

This Java code implements a basic Zoo Management System. It defines classes for `Animal` and `Enclosure`, along with subclasses for different animal types (Australian, European, African). The code includes methods to handle animal names, IDs, and weights. The `Enclosure` class manages enclosure details, opening hours, and entry fees. The `main` method writes sample zoo data to a text file and provides a menu-driven interface to display zoo information and viewing prices. The code demonstrates file handling to store zoo data and uses object-oriented principles to structure the zoo's various components, offering a foundational example for managing zoo-related information. The system is capable of displaying zoo information and entry fees and operating hours.
