Example project for TCP and UDP communication with server and multiple clients using Java

How to run the game:

1. Start the server - run "main" method in /src/main/java/game/server/Server.java
2. Start a client - run "main" method in /src/main/java/game/client/Client.java

• You can run multiple clients
