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 ObjectOutputStream(s.getOutputStream()); 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.
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 like this: String str = "Navid Reddy " (-> 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)
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?
Did you ever get an answer to this question? Im trying to find out how to send coordinates from one device to another, and display those coordinates in a map on that other device.
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
+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 (clientSocket.getOutputStream()); osw.write(message); osw.close(); Is it necessary to create PrintWriter object? Thanks
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.
Thanks for tut. Just few questions. Do you have tut about JSP? To learn JSP ,do someone need to learn JAVA first. What is different b/w java nd JSP? Thanks
I can't main class with different name as project name and this then gives error on making 2 main class files in same project. I am working in net beans. what should I do ? please help ..

Hi, Could please tell me how to do this client-server in 2 different system in same network? I tried to give the IP of server in client, but it didnt work?
Hi Navin, thanks for this wonderful video. How would I transfer a List of elements from a server to client by using DataInput/OutputStream. I tried with out.write(list), it does not work. Your reply will be highly appreciated.
In client class. insert a newline character in end of your data. e.g println("Nanin Reddy "); because readLine() function need a newline character to stop reading.
HI, This is bhagvan. Iam getting NetworkOnMainThreadException when rnning this code. I was tried in google but there are no source. can you please tell me why this coming. give the link for referance if possible. Thank q
I have written the same code. But the server never connect with client, although their port are same.I have checked the code many times. But I can't find the problem yet.
IDK why people uses JAVA for socket Programming as there is python which is very easy and simple to use then ,I'm just here because tommorow is my exam :/

You are the best java lecturer on entire website.
Best instructor ever and ever. I'm a big fan of you sir. thanks a lot.
you are doing very great man. I am learning too much from your channel.

Thanks a lot. Just adding "
" worked for me.
@@musfikuroli Thanks a lot bro you saved me from going on an endless hunt on StackOverflow
Edit: You too @G-L
didnt worked bro
I think you missed "os.close(); " in the client program, right?
as long as i know it is not necessary to close every reference.
But it was necessary in my case. as without it the client thread was being closed even before it flushed the data.
tnx man . .i just found my error . after looking . to run my prog so many times
Thanks man
Saved my time. Thanks!

we can also use out.println() in place of os.write().
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.
Why my program get terminated when I run client class ......
Server runs fine
Wht should I do
In the Client program ,you have created Printwriter but you did not use it at all.
os.write(str) line should be replaced with out.println(str) to work properly on some systems.
Same problem was with me........thanx for ur help
Eren L

Hi Navin, thanks for this wonderful video. How would I transfer a List of elements from a server to client by using DataInput/OutputStream. I tried with out.write(list), it does not work. Your reply will be highly appreciated.
Exception in thread "main" java.net.SocketException: Connection reset
sir how to handle this?
where do we need "out" variable then?
Thank You Sir
What was the purpose of creating a PrintWriter object??
i did excatly whats in your program. and an erroe accured is says. "java.net.SocketException: connection reset"
how can i solve this error?
in client program there is a os.close(); missing after flush()... I had the same problem
In client class. insert a newline character in end of your data. e.g println("Nanin Reddy
");
because readLine() function need a newline character to stop reading.
Can anybody tell where is the next video, please?

You need to close the outputstream object and socket object
Add these 2 lines after os.flush();
out.close();
s.close();
only out.close() is enough.
yeh..it works
Why have you created PrintWriter object ,, out ,, and you dont use it?
