Chat functionality in Java?

Question

Java

Hello, I started writing a console chat in java. Tell me, what functionality should such a chat have so that it could be added to the portfolio for java-junior?

Answer 1

Take any open standard and implement compatibility with it. For example, take XMPP and write a minimum compatible client from scratch.
As mentioned above, they will be judged by the code and architecture. If the bike is your own, then it will be somewhat more difficult for people to understand what is happening there, in the case of some kind of standard, it will be much easier for them to understand the meaning of the code and evaluate the style / architecture / code already.
