A scalable client-server Rock–Paper–Scissors game built in Java using the UDP protocol.
Features a custom dependency injection (DI) container, microkernel modularity, and a PacketDispatcher for efficient client routing.
Supports multiple clients, queuing them until paired for a two-player match.

• UDP protocol for lightweight, connectionless communication
• Custom DI container for dependency management
• Microkernel architecture enabling modular extensions
• PacketDispatcher to identify and route packets to the correct client
• Client & message queues for pairing and concurrency management
• Two-player gameplay with server handling many clients simultaneously

• Server

  • Listens for UDP packets
  • Uses PacketDispatcher to route messages
  • Manages client queue and pairs players for matches
  • Applies DI container for modular lifecycle management

• Client

  • Connects to server via UDP
  • Sends chosen moves (Rock, Paper, Scissors)
  • Receives results and game state updates
