各位前辈,小弟想问一个同步的问题.

Question

怎样在一个类中同时使用serversocket和clientsocket呢?

Answer 1

ServerSocket svrsck;
ClientSocket cltsck;
就可以了。

Answer 2

package cs;import java.net.*;
import java.io.*;public class socketclient{

public static void main(String[] args){
String str;
try{

InetAddress addr=InetAddress.getByName("127.0.0.1");
Socket socket = new Socket(addr,8001);
System.out.println("Socket: "+socket);

InputStream fin=socket.getInputStream();
OutputStream fout=socket.getOutputStream();

InputStreamReader isr=new InputStreamReader(fin);
BufferedReader in = new BufferedReader(isr);

PrintStream out = new PrintStream(fout);
InputStreamReader userisr = new InputStreamReader(System.in);
BufferedReader userin = new BufferedReader(userisr);

while(true){
System.out.print("发送字符串:");
str=userin.readLine();
out.println(str);

if(str.equals("end")) break;
System.out.println("等待服务器消息....");
str=in.readLine();
System.out.println("服务器字符串:"+str);
if(str.equals("end")) break;
}//while
socket.close();
//server.close();
} //try
catch(Exception e){
System.out.println("异常:"+e);
}
}
