帮帮忙！！

Question

import java.net.*;
import java.io.*;
class TestTalkServer
{
public static void main(String[] args)
{
try{
    ServerSocket ss=new ServerSocket(8888);
Socket s=s=ss.accept();
}catch(Exception e)
{
e.printStackTrace();
}
try{
DataInputStream dis=new DataInputStream(s.getInputStream());
DataOutputStream dos=new DataOutputStream(s.getOutputStream());
String talk=null;
System.out.println("client:"+dis.readUTF());
DataInputStream dis1=new DataInputStream(System.in);
talk=dis1.readUTF();
while(!talk.equals("bye"))
{
if(dis.readUTF()!=null)
{
System.out.println("client:"+dis.readUTF());
}
dos.writeUTF(talk);
System.out.println("server:"+talk);
talk=dis1.readUTF();
}
}catch(Exception e2)
{
e2.printStackTrace();
}
}
}这是Server端编译时出现“找不到符号s的错误”
import java.net.*;
import java.io.*;
class TestTalkClient
{
public static void main(String[] args)
{
try{
Socket s=new Socket("127.0.0.1",8888);
}catch(Exception e)
{

}
try{
DataOutputStream dos=new DataOutputStream(s.getOutputStream());
DataInputStream dis=new DataInputStream(s.getInputStream());
DataInputStream dis1=new DataInputStream(System.in);
String talk=null;
talk=dis1.readUTF();
System.out.println("client:"+talk);
while(!talk.equals("bye"))
{
dos.writeUTF(talk);
if(dis.readUTF()!=null)
{
System.out.println("server:"+talk);

}
talk=dis1.readUTF();
}
}catch(Exception e1)
{
e1.printStackTrace();
}
}
}  
这是Client端也出现找不到符号s的错误请帮帮忙看一下谢谢！！！

Answer 1

//Socket s=s=ss.accept();这行代码有问题，改成下面的
Socket s = ss.accept();

Answer 2

不好意思上面Socket s=s=ss.accept();打错了是Socket s=ss.accept();

Answer 3

各位讨论半天 不知道 s 在 try {}catch 块中， 不是外面当然找不到啊，先看看基础吧
