A modular client-server calculator built with Java.
Features TCP communication, a custom dependency injection (DI) container, and a microkernel architecture.
Implements Factory and Strategy design patterns for extensibility, maintainability, and clean separation of concerns.

• TCP communication between client and server
• Custom DI container for dependency management
• Microkernel architecture enabling modular extensibility
• Factory pattern for flexible object creation
• Strategy pattern for dynamic behavior injection

The system is divided into two main modules:

• Server

  • Listens for TCP requests
  • Uses DI container to manage dependencies
  • Executes calculation strategies via microkernel plug-ins

• Client

  • Sends calculation requests over TCP
  • Receives and displays results
  • Can be extended with new interfaces (GUI, etc.)

• Java
• TCP protocol
• Custom DI framework
• Factory & Strategy design patterns
• Microkernel modularity
