Socket Programming in Java One Way

Define IP address and port number for client and server connection.
Server socket is used for multiple client connection with server.
Every client requires one socket.
We have to create two classes one for client and one for server.

Some helpful tips:
1. Temporarily disable your firewall to prevent firewall from stopping network traffic on your chosen port (9999)

2. You can use
ObjectOutputStream os = new
PrintWriter out = new PrintWriter(os);
out.println(msg);
os. close();
in your client.Telusko corrects his mistake in the next video called "Socket programming in Java Two Way".

But this also works as seen in the video, so actually you don't need the PrintWriter object:
os.write(msg);
os.close();

3. IMPORTANT: Start your SocServer first and SocClient next!

4. You have two consoles, because you start two programs. The server is printing the incoming message too its console. So when you see no message, you're probably looking in the console of the client.

man u r excellent i wasted 2days(12hours) on "what is socket " and u explained just in 2 min and u also told how use socket i subscribed and thank u very much, i wanted to create a client android app can use this coding?

If you get a Error looking like this: java.net.ConnectException: Connection Refused -> It could have following solutions: 1. start server before client, 2. turn off your firewall, or, which worked for me: 3. in your Clien class, make the String end the line with appending \n like this: String str = "Navid Reddy\n" (-> br.readLine() expects a full line (at least on my computer?), I don't know why the code shown in the tutorial seems to work for so many people without ending the line)

Hi navin, i am new to java. Can you tell me what is the use of out variable in socClient program? I mean purpose, as it's not being used... Thank you so much for making such video. You have changed the way of learning and studying. Thank you and and I mean it seriously

[saadmanahmed]

exquisite illustration as usual.Your keynotes have always rendered me some good coding understanding

[marcusleeeugene]

Great tutorial! You helped me understand about TCP connections! :)

[royrao]

I think you missed "os.close(); " in the client program, right?

[trueIndianJaiHind]

Sir, Thanks for such a good tutorial.

[Mreven]

Hey buddy,
Grate and simple tutorial . BTW, I did not get it why did you create Print Writer, because you never used it .
Thx in advance.

[xGrofx]

Best tutorial on the subject! Thanks mister!

[koushikshomchoudhury]

My first networking program! Thanks :) tutor!

[PratikShende]

we can also use out.println() in place of os.write().

[vanrensburg]

Nicely explained thank you, can you talk about how a server can generate a unique ID for client that connects and how one client can communicate with another, through the server.

+Telusko Learnings Why was the PrintWriter created? It was never used. Also I tried without PrintWriter. It worked fine for me.
OutputStreamWriter osw = new OutputStreamWriter
osw.write(message);
osw.close();
Is it necessary to create PrintWriter object?
Thanks

[xiaoyingsun]

Thanks for the generous share. Btw which kind of Projects did you initiate?

Hi Naveen, you are a life saver. Any plans on making creating JavaScript playlist?
