This communication system features a Center class acting as a hub to register users, manage unique IDs, and facilitate message exchange. Users, represented by classes like Car and Cat, implement the User interface with methods for messaging and message storage, using a HashMap for efficient user lookup and message record-keeping in text files.

Communication System

A messaging system where different users can communicate with each other. The main components of the system are:

• Center class: Acts as the central hub for registering and storing users.
• User interface: Defines the behavior of users in the system.

Each user (e.g., Car, Cat, Cloud, and Cup) implements the User interface with unique characteristics.

Center Class

The Center class maintains a map of registered users, providing methods for:

• Adding users
• Displaying the user list
• Sending messages between users
• Handling message storage in text files

The IDGenerator class ensures each user receives a unique ID upon registration. The primary data structure is a HashMap, where unique user IDs serve as keys, and user objects are values, enabling efficient user lookup.

User Interface

The User interface defines methods like sendMessage, saveMessage, and getRandomQuote, implemented by user classes. These methods enable users to:

• Send messages to other users
• Save received messages
• Retrieve random quotes

Each user has a unique ID, communicating with others through the Center class. Messages exchanged are stored in text files for record-keeping.

Overall, this code creates a messaging system facilitating user interaction through message exchange, with the Center class managing communication and message storage.
