rajeesudh / java-chat Goto Github PK

A console-based chat client & server, built using strong TDD throughout. It uses Java 8, JUnit and Hamcrest matchers, but has not other dependencies.

This is a teaching application designed to show how real-world applications can be structured. There are a number of areas in which the application can be extended, and you are encouraged to do so in your own fork. Suggestions for improvements are listed below.

• JDK 8
• Maven

Run mvn package to compile, run tests and package the application. The jar file will be output in target and named chat-1.0.jar.

1. First build the application and then change to the target directory. If you are in the project root then you can do this with cd target.

2. Run the following command.

java -jar chat-1.0.jar server <port number>

If you do not specify a port number the system uses a default of 3000. If the port is already in use, you will see an "Address already in use" error.

1. First build the application and then change to the target directory. If you are in the project root then you can do this with cd target.

2. Run the following command.

java -jar chat-1.0.jar client <address> <port number> <username>

If the name is already in use you will see an error.
