# Quine over network [closed]

## Write a program, that sends its own source code over network.

Network example is TCP/UDP or web socket. Ethernet, Bluetooth, Wi-Fi and internet over USB are allowed.

No need to write receiver program. You can use any encoding protocol, but decoder will be realizable.

# Rules

• Network is not a stdout, screen, USB, UART, GPIO or same.
• The program must be at least 1 byte long.
• No input or accessing source from file system.
• No extra software to send stdout to network like ssh.
• This is , shortest code wins.

• Is there a specific host we need to send to? – Kevin Cruijssen Jul 3 '17 at 7:23
• @KevinCruijssen you can use any, but it will be able to recive message – Евгений Новиков Jul 3 '17 at 7:24
• Could you give a valid example-host? – Kevin Cruijssen Jul 3 '17 at 7:43
• @KevinCruijssen localhost – Евгений Новиков Jul 3 '17 at 7:52
• This seems like the kind of generalised quine where the quine part adds nothing to the networking part and the networking part adds nothing to the quine part. – Martin Ender Jul 3 '17 at 8:12

• The String s contains the unformatted source code.
• %s is used to input this String into itself with the s.format(...).
• %c, %1\$c and the 34 are used to format the double-quotes.
• s.format(s,34,s) puts it all together

Slightly modified with print to prove it's a quine:
Try it here.

• Well is this considered as a quine? Sorry, I'm new to this. But you've just copypasted your code in a string you print afterwards >_< I was seeing quine as some complicated algorithm playing with generated bytecode. +1 though ^^' – V. Courtois Jul 3 '17 at 8:41
• @V.Courtois Thanks for the +1. :) Although most programming languages have a built-in for quines, Java does not. Pasting the entire code into a String and using x=s=s.format(s,34,s);for(List l=Arrays.asList(x.split(""));!x.equals(s);s=s.join("",l)); is a.f.a.i.k. one of the few ways to actually make a 'quine' in Java. Currently this is still acceptable as a quine, although it has been mentioned here in the "Eval quines" section of this Meta post, with the question if we should still allow this: We need a new proper quine definition. No conclusion of it yet. – Kevin Cruijssen Jul 3 '17 at 11:20
