服务器程序:
import java.io.*;
import java.net.*;
public class Server3 extends Thread
{
Socket socket1;
public Server3(Socket s)
{
socket1=s;
start();//Calls run()
}
public void run()
{
try
{
BufferedReader in=new BufferedReader(new InputStreamReader(socket1.getInputStream()));
PrintWriter out=new PrintWriter(new BufferedWriter(new OutputStreamWriter(socket1.getOutputStream())));
for(int i=0;i<5;i++)
{
String str=in.readLine();
System.out.println("Server receives"+str);
out.println("Server return back"+str);
}
System.out.println("closing...");
}
catch(IOException e)
{
System.err.println("IOException");
}
finally
{
try
{
socket1.close();
}
catch(IOException e)
{
System.err.println("Socket not closed");
}
}
}
static final int PORT=8000;
public static void main(String[] args) throws IOException
{
ServerSocket s=new ServerSocket(PORT);
System.out.println("Server Stared");
try
{
while(true)
{
Socket socket1=s.accept();
try
{
new Server3(socket1);
}
catch(Exception e)
{
socket1.close();
}
}
}
finally
{
s.close();
}
}
}

客户端程序:
import java.net.*;
import java.io.*;
public class Client3 extends Thread
{
int threadNumber;
Socket socket1;
public Client3(int i,Socket s)
{
System.out.println("Making thread="+i);
threadNumber=i;
socket1=s;
start();
}
public void run()
{
try
{
PrintWriter out=new PrintWriter(new BufferedWriter(new OutputStreamWriter(socket1.getOutputStream())),true);
BufferedReader in=new BufferedReader(new InputStreamReader(socket1.getInputStream()));
for(int i=0;i<5;i++)
{
out.println("data from client:" + threadNumber + "=" + i);
//for(int i=0;i<5;i++)
String str=in.readLine();
System.out.println(str);
}
}
catch(IOException e)
{
try
{
socket1.close();
}
catch(IOException e2){}
}
}
public static void main(String[] args)throws IOException
{
for(int i=1;i<11;i++)
{
new Client3(i,new Socket(args[0],Integer.parseInt(args[1])));
//new Client3(2,new Socket(args[0],Integer.parseInt(args[1])));
}
}
}

Posted by: rjyang Posted on: 2005-03-08 16:46 本应该是客户端开十个线程建立十个连接分别向服务发送5个数据,但是实际上每个线程建立连接后,客户端向服务器只发送了一个数据,然后所有线程就停下来了,不知道问题出地哪?请高手指教!!!!!
