Multithreaded messaging server

ABOUT

This is a console version of a simple chat that allows you to exchange messages with other clients connected to the server.

Main features:

• ✅ Separated input and output message streams
• ✅ Sending messages in JSON format
• ✅ Save an unfinished message and move it to the next line with the ability to edit
• ✅ Full support for command line parameters and interactive parameter input

How to start it?

Since Java requires the presence of the main class Main, for ease of launch there is the possibility to initialize the server or client classes using command line arguments. To get help information, pass the --help parameter.

Important

Make sure you have Maven installed, which is required to build this project. (See Dependencies)

Starting the server

make
java -jar target/multithreaded-server.jar --mode server

Starting the client

make
java -jar target/multithreaded-server.jar --mode client

Note

There is also an interactive class selection in the absence of command line parameters.

$ make && java -jar target/multithreaded-server.jar

Select startup mode
1 - Server
2 - Client
