Java Networking - 3 - Chat Server & Client

Hey everyone, in this video I teach you how to make a chat server and client!

[MrNUKECOW]

Seriously great vid, one of the best explanations ive ever seen

I cant send a message when i click the button, it stopped working around the time you needed to find out why the messages where not working. I then changed it to what you changed it to and then it stopped sending messages.

when I started writing "private static I get a warning on public static void saying "The Method has constructor name". How do I get rid of it? 

[dineshsri]

can u pls share how to chat  from different computers ?

[nicklasost]

Hey, why do you make the fields in your various packet classes public ? Its not best practice. Is it not better to use setters/getters and custom constructors?

can you make a short video, about how we set up our server onlinie?
that we could send our friend one client and chat with him over the internet

Who remembers that one chat website called NeoChat or something, you pick an avatar as your icon and chat just like Kik??

So I got the server to work, and when I connect it works but then when i try to send a message the message doesn't go through. I have followed your code verbatim. Any suggestions?

[madmenyo]

There is a pretty big difference in using the passed Connection parameter to get the client ID or looking it up in a hashmap. Looking up strings in a hashmap is not very efficient, having thousands of clients and each time someone connects, disconnects or sents a message you have to lookup the connection in the hashmap would be very inefficient. Only use the hashmap with the clients when you really need it, and that should not be very often I think. If you want to sent a private message you are better of sending the ID allong with another package that stores your name, your message, clients name and clients ID. I know you are most probably aware of this, just pointing it out for others.

Hi, I found Kryonet very useful and interesting and was wondering if you could continue the series ( or if you know any series that make a game to direct me) to help in development of client/server applications. Please post the source code too

Hey your vid are awesome, do i need any devices for this tutorial?

[orionlamothe]

Nvm i fixed that but it doesnt say disconnected in the chat instead it says it in the console itself.

[fatimayassin]

Thanks a lot of your video it is really very helpful. I keep seeing the msg "Cannot Connect! Try Again. " i think the problem is the server IP and the port number. Can you please  explain more how to make it run on my device and how to make my device the localhost as well.
