socket 编程总是不能实现！！求助~~~~

Question

这是我的代码
客户端：import javax.swing.*;
import java.awt.*;
import java.lang.*;
import java.net.*;
import java.util.*;
import java.io.*;
public class client implements Runnable{
    
    BufferedReader in;
    PrintWriter out;
    ObjectInputStream fromclient;
    Socket toserver;
    
    
    Thread th=new Thread(this);
public client(){

th.start();
}

public static void main(String args[]){
   new client();
} String s=new String();
public void run(){

try{

InetAddress addr=InetAddress.getLocalHost();
Socket toserver=new Socket(addr,8000);

BufferedReader in=new BufferedReader(new InputStreamReader(toserver.getInputStream()));
PrintWriter out=new PrintWriter(new BufferedWriter(new OutputStreamWriter(toserver.getOutputStream())));
//ObjectInputStream fromclient=new ObjectInputStream(toserver.getInputStream());
    out.write("receved");
    
//fromclient.readObject(cust);
//System.out.println();
   }
catch(Exception e2){
System.out.println(e2);
}


}}
服务器端：
import javax.swing.*;
import java.awt.*;
import java.io.*;
import java.lang.*;
import java.net.*;
import java.awt.event.*;
 public class server extends Thread{
 
 
  ServerSocket serversocket;
  Socket socket;
  public server(){
 
  Thread serth=new Thread(this);
 
  this.start();
  }
 
 
  public static void fail(Exception e,String str){
 
  System.out.println(str+"."+e);
  }
  public void run(){
  try{
  ServerSocket serversocket=new ServerSocket(8000);
  while(true){
 
    Socket socket=serversocket.accept();
    System.out.println("server started.......");
  connection con=new connection(socket);
  }
  }
  catch(Exception e1){
 
  fail(e1,"not listenning");
  }
 
 
 }
  public static void main(String args[]){
 
 
  server s=new server();
 
  System.out.println("i am server..");
  }
  }
 class connection  extends Thread{
 
  protected  Socket netclient;
  protected  BufferedReader fromclient;
  protected  PrintStream toclient;
 
  public static void fail(Exception e,String str){
 
  System.out.println(str+"."+e);
  }
 
 
 
    public connection(Socket socket){
    
    Thread t=new Thread(this);
 
  netclient=socket;
 
  t.start();
 
 
  }
  public  void run(){
    try{
  fromclient=new BufferedReader(new InputStreamReader(netclient.getInputStream()));
  toclient=new PrintStream(netclient.getOutputStream());
 
      String b="you shen me shi qing ma?";
  toclient.println("recieved from:"+b);
      
        String s=fromclient.readLine();
     System.out.println(s);
  }
 
  catch(Exception e3){
   System.out.println(e3);
 
  }
 
  finally{
  try{
  netclient.close();
     }
  catch(IOException e){}
  } 
  }
  }
 
 
 
 
编译可以通过，但服务器端的控制台要报错为：java SocketException connection reset
 
 
 
 
 
    

Answer 1

out.write("receved");改成out.println("received");试一下

Answer 2

out.println();
和对应
out.readLine();

Answer 3

给你俩个程序你看一吧
import java.io.*;//服务端
import java.net.*;
import java.lang.*;
import java.util.*;
public class server2{
public static void main(String args[]){
String h;
try{
ServerSocket client=new ServerSocket(4001);
while(true){
Socket socket1=client.accept();
BufferedReader str=new BufferedReader(new InputStreamReader(socket1.getInputStream()));
PrintStream p=new PrintStream(new FileOutputStream("fddjx444.java"));
PrintWriter p1=new PrintWriter(socket1.getOutputStream());
while((h=str.readLine())!=null){
p.println(h);
p.flush();
client.close();
}
}
}
catch(IOException e){
System.out.println(e);
}
}
}
//客服端
import java.io.*;
import java.net.*;
import java.lang.*;
import java.util.*;
public class socket2{
public socket2(){
String string1;
byte buf[]=new byte[2056];
try{

File f=new File("fddjxllren3.java");
FileInputStream f1=new FileInputStream(f);
int s=f1.read(buf,0,2056);
string1=new String(buf,0,s);
PrintStream p2=new PrintStream(client2.getOutputStream());
p2.println(string1);
client2.close();
}
catch(Exception e){
System.out.println(e);
}
}
public static void main(String args[]){
