Design a menu manager with enums

Design and implement a console-based restaurant menu management program. Requirements: (

2. Support addItem(name, price, category), updatePrice(name, newPrice), removeItem(name), listAll(), and listByCategory(category). (
3. Print items using each object's toString() rather than accessing fields via getters; list output grouped by category and sorted alphabetically within each category. (
4. Choose data structures to achieve O(
5. add/update/remove by name and O(k log k) listing within a category (k = number of items in that category). (
6. Provide a simple CLI that reads commands from stdin and executes them, plus basic unit tests.
