Extra 13. Multithreaded networking

Main steps

• Review theory
• Implement chat server
• Implement chat client

Review theory

1. Review presentations:

   1. Threads
   2. Chat

Implement chat server

1. Investigate jtm.extra13 package
2. If necessary, change value of static final int port = 7700 variable in ChatServer.java class and value of port key in src/resources/appplication.properties configuration file to different number e.g. 7701
3. Implement class ChatServer to pass unit tests

4. Server could be checked using nc program, e.g. following:

   nc 127.0.1.1 7700

5. To check if server is listening on necessary port, run command:

   netstat -antp|grep 7700

6. If necessary, server can be killed with command:

   kill -9 pid
   where pid is process id from the previous command

Implement chat client

1. Investigate package jtm.extra14
2. If necessary, change value of static final int port = 7700 variable in ChatClient.java class and value of port key in src/resources/appplication.properties configuration file to different number e.g. 7701
3. Implement ChatClient class to pass unit tests
