I have written a simple java code using sockets to get input from a local txt file and save it by creating another txt file in my storage elsewhere. I am using my client program to send the data and the server program to receive the data and save it. I run my server program before my client program and after running that client program, I get my output in the console that the connection has been established (I have written that in my code while trying to debug it) but, after the connection established message, I am getting The following error in my Server program: Exception in thread &quot;main&quot; java.net.SocketException: Connection reset at java.base/sun.nio.ch.NioSocketImpl.implRead(NioSocketImpl.java:323) at java.base/sun.nio.ch.NioSocketImpl.read(NioSocketImpl.java:350) at java.base/sun.nio.ch.NioSocketImpl$1.read(NioSocketImpl.java:803) at java.base/java.net.Socket$SocketInputStream.read(Socket.java:982) at Assignment_2.DA_FileServer.main(DA_FileServer.java:16)  Following is my Client program code:      public class DA_FileClient {         public static void main(String args[]) throws Exception{             Socket cs = new Socket(&quot;localhost&quot;,5050);              byte[] b = new byte[12345];             FileInputStream fis = new FileInputStream(&quot;D:\\Coding Practice\\Source.txt&quot;);             fis.read(b,0,b.length);             OutputStream os = cs.getOutputStream();         }     }   and this is my Server program:      public class DA_FileServer {         public static void main(String args[]) throws Exception{             ServerSocket ss = new ServerSocket(5050);             Socket cs = ss.accept();             System.out.println(&quot;Connection Established!&quot;);              byte[] b = new byte[12345];             InputStream is = cs.getInputStream();             FileOutputStream fos = new FileOutputStream(&quot;C:\\Users\\FoxSinOfGreed\\Desktop\\Destination.txt&quot;);             is.read(b,0,b.length);             fos.write(b,0,b.length);         }     }     ```  P.S. I am using IntelliJ Idea Community Edition
I am getting the following error trying to read from a socket. I'm doing a readInt() on that InputStream, and I am getting this error. Perusing the documentation this suggests that the client part of the connection closed the connection. In this scenario, I am the server.  I have access to the client log files and it is not closing the connection, and in fact its log files suggest I am closing the connection. So does anybody have an idea why this is happening? What else to check for? Does this arise when there are local resources that are perhaps reaching thresholds?    I do note that I have the following line:  socket.setSoTimeout(10000);   just prior to the readInt(). There is a reason for this (long story), but just curious, are there circumstances under which this might lead to the indicated error? I have the server running in my IDE, and I happened to leave my IDE stuck on a breakpoint, and I then noticed the exact same errors begin appearing in my own logs in my IDE.  Anyway, just mentioning it, hopefully not a red herring. :-(
Add leading zeroes to number in Java? How can I start the Blood on the Ice quest? I am currently part of the Stormcloaks and just finished Rescue from Fort Neugard. The Jarl wants to make me a thane and is telling me to buy a house, but his steward is telling me the house is unavailable due to some unpleasantness. I have already completed the 5 quests to help people of Eastmarch.  From what I can see online, I need to begin the Blood on the Ice quest. It is supposed to begin by walking in the windhelm graveyard at night, however every time I go there I don't see anyone.  Someone online said it's possible to miss the scene that triggers the quest if you go into Windhelm and leave without triggering it, but I am hoping this isn't the case. I am in Windhelm a lot because the Enchanting table, Blacksmith, and Fence are all in one location, so find it very convenient. The lady who is supposed to be murdered in the Graveyard (Susanna) is still alive in Candlehearth Hall, so I think I'm not bugged.  The wiki suggests that you have to "The quest will initiate after you entered Windhelm four times from another hold", however I have entered and left quite a few times during the course of my game and know I've been here way over 4 times.  I tried pickpocketing the key, however I don't automatically get the quest on entering the house, and there are a bunch of "Investigate InvestigationTarget" spots in the house. Also, I was reading the Butcher's journal and he was saying he almost caught Susanna when she left Candlehearth, however I have never seen her leave Candlehearth. Perhaps my glitch is she never leaves? I'll have to head to Windhelm on another character and check it out.  Also, I saw something online saying this quest won't trigger if you go past 245 in-game days. Would someone be able to confirm this for me? (Have the XBox version, so waiting 245 days is annoying)  Can someone tell me the exact steps to begin this quest? Manga where the protagonist need to solve girl's quests Can someone tell me the manga in which the protagonist is teleported to an alternative world where he needs to make the girls fall in love with him, then he gains some skills like an invisible sword. Then, when he finishes these &quot;quests&quot;, he will be able to bring one of them to the real world. He has the ability to save and load like checkpoints of games. What does "65" mean? K-2SO beats up the troopers easily. Up in the sky, the bombers are preparing to attack. Just as they start the attack run, TIE fighters come in from the shield and swarm the rebel fleet.

Can an infinite set A be larger than an infinite set B but still have the same cardinality? Definition. Two sets have the same cardinality iff they can be put into one-to-one correspondence; or,     $$A \simeq B \iff |A| = |B| $$    This definition applies to infinite as well as to finite sets. It follows from the last three definitions that set $A$ has a larger cardinality than set $B$ iff both    a proper subset of $A$ and the whole of $B$ can be put into one-to-one correspondence the whole of $A$ cannot be put into one-to-one correspondence with any proper subset of $B$.   From: A Crash Course in the Mathematics Of Infinite Sets Peter Suber, Philosophy Department, Earlham College  The last part specifically refers to proper subsets of $B$.  That excludes at least one subset of $B$, namely $B$.  So, is it possible that the whole of A cannot be put into one-to-one correspondence with any proper subset of $B$ but may with $B$ itself? Why did he not say "any subset of $B$"? How can I detect if I'm in a subshell? Do I need a visa for a connecting flight to Japan? I'm going to the Philippines this October and would like to layover in Japan. I found a reasonably priced ticket with a 15-hour layover to Haneda, however, I have to transfer to Narita.

Thank you! number theory about index Given the congruence $x^3 \equiv a \pmod p$, where $p \geq 5$ is a prime and $\gcd(a,p)=1$, prove the following:   If $p \equiv1 \pmod 6$, then the congruence has either no solutions or three incongruent solutions modulo $p$ If $p \equiv5 \pmod 6$, then the congruence has a unique solution modulo $p$   Help me...  I don't know what I learn because Prof teaches so quickly.  So I need your help to organize my thoughts. Is "mens" a valid word? I've been living in Ireland for almost a year now and I start noticing they use the word "mens" a lot. I can see it used in:   Shops, to denote the area where you can find men's clothes In sport, when they talk about "mens team".    My guess is just that they are lazy about the use of quotes, so that mens should actually be men's. However, there may be some rule I'm not aware of. So, is "mens" only limited to Irish English? When I'm allowed to use it? How to correctly install libpng12-0 on the Ubuntu 19.10? Can the graph of a bounded function ever have an unbounded derivative? Is there a VB.NET equivalent for C#'s '??' operator? Is there a VB.NET equivalent for C#'s ?? operator? I have an associative array in the form key =&gt; value where key is a numerical value, however it is not a sequential numerical value. The key is actually an ID number and the value is a count. This is fine for most instances, however I want a function that gets the human-readable name of the array and uses that for the key, without changing the value.  I didn't see a function that does this, but I'm assuming I need to provide the old key and new key (both of which I have) and transform the array. Is there an efficient way of doing this?

Basicly, what I whant is the as on the screens, but wo any artifacts :)   Also, here's the .blend file, cause I assume I didn't make myselt 100% clear. Why do some bad traits evolve, and good ones don't? If a trait would be advantageous to an organism then why hasn't it evolved yet?  Conversely, if a trait is not advantageous or mildly disadvantageous, why does it exist?  In other words why does evolution not make the organism more "perfect"?    This is a general question that would be applicable for any kind of trait. Please keep the answers precise and scientific.
