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.

You are the best java lecturer on entire website.

[@faiseen_talks]

Best instructor ever and ever. I'm a big fan of you sir. thanks a lot.

[@vinayakgarments9182]

Watching this video in 2023..

[@alixaprodev]

you are doing very great man. I am learning too much from your channel.

[@royrao951]

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

[@arveersingh9728]

as long as i know it is not necessary to close every reference.

[@abhijeetrastogi7087]

But it was necessary in my case. as without it the client thread was being closed even before it flushed the data.

[@programmingforbeginners8706]

tnx man . .i just found my error . after looking . to run my prog so many times

[@kundan625]

Thanks man

[@moonbrush5]

Saved my time. Thanks!

[@g-l8492]

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)

[@musfikuroli]

Thanks a lot. Just adding " " worked for me.

[@JohnDoe-ml2zy]

@@musfikuroli Thanks a lot bro you saved me from going on an endless hunt on StackOverflow Edit: You too @G-L

[@Cowboy1Brian]

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.

[@xGrofx]

Best tutorial on the subject! Thanks mister!

[@parwana1000]

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

[@marcusleeeugene]

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

[@Mr47even]

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.

[@cassi4790]

that was very helpful!tysm

[@ziddy26]

+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

[@ashwanikumar4288]

I also have the same doubt

[@curiousgeorge6307]

I was also wondering the same thing

[@jintujose_28]

Could you please create a video for how to create a directory on the server side using socket programming in java

[@PratikShende91]

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

[@chhaylin3210]

Great video

[@vanrensburg3760]

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.

[@xiaoyingsun4581]

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

[@cringelord511]

java project

[@ashishposte8192]

In the Client program ,you have created Printwriter but you did not use it at all.

[@ishajha1243]

Thank You Sir

[@sauravmukherjeecom]

Nice. Do u have anything about Java XML parsing?

[@eren96lmn]

os.write(str) line should be replaced with out.println(str) to work properly on some systems.

[@ayushpratik4208]

Same problem was with me........thanx for ur help

[@ALSAHER79]

[@ankushroy919]

do we need same package for client and server?

[@hussain1755]

why did u create printwriter "out" ?? you never used it in the client socket

[@SM-vo5gj]

this is what i was wondering, and possibly is source of problems a couple comments up- with os.write ... should it have been out.write?

[@hemanth6951]

hi,i am your fan from long year,but you never noticed me

[@shubhamsangale890]

Sir, even if pass value "true" with the str in printwriter it works!!! can you please let me know the reason??

[@onlyforstudy7183]

Plzz more explain about program

[@varundurvasula7536]

Can we achieve this by using scanner? (instead of bufferedreader)

[@andevinay1494]

where you have used Print Writer object out in the client class

[@anwarulkaium1101]

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.

[@AYAN454]

where do we need "out" variable then?

[@hristoplamenov1942]

Hello guys, just one question - why it deletes the information in the client side after i run it ? It shows the Navin Reddy and then black screen :/

[@JohnDoe-ml2zy]

I have a problem: When I run the client side, it says "Connection Reset" error on the server console. How can I resolve this?

[@DirtyDan612]

When I run the server I get the two statements to print but when i run the client nothing happens, any ideas why? My code is exactly the same.

out.close(); after os.flush();

[@wilburtmoreno469]

i did excatly whats in your program. and an erroe accured is says. "java.net.SocketException: connection reset" how can i solve this error?

[@duff2233]

in client program there is a os.close(); missing after flush()... I had the same problem

[@gouravthapa5815]

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.

[@akhilmishra624]

[@amartyachakraborty5739]

" java.net.SocketException: Connection reset " sir i am getting this error .. what to do?

[@arunberlin]

You need to close the outputstream object and socket object Add these 2 lines after os.flush(); out.close(); s.close();

[@susannaantinyan4595]

only out.close() is enough.

[@SourabhMaybhate]

yeh..it works
