求教2个程序，一个运行于客户端，一个运行与服务器端

Question

如果不是广域网可以用socket；用远程调用(RMI)也可以；用JMS要相应的服务器。

Answer 1

大家有程序吗？我想看看，就是socket编程的

Answer 2

//服务端程序
import java.net.*;
import java.io.*;
public class serverscoket{
public static void main(String agrs[]){
ServerSocket serverSocket;
Socket socket;
BufferedReader br;
BufferedWriter bw;
String inString,outString;
try{
serverSocket=new ServerSocket(7777);
socket=serverSocket.accept();
br=new BufferedReader(new InputStreamReader(socket.getInputStream()));
bw=new BufferedWriter(new OutputStreamWriter(socket.getOutputStream()));
inString=br.readLine();
outString="You have said"+inString;
bw.write(outString);
bw.flush();
br.close();
bw.close();
serverSocket.close();
socket.close();
}
catch(Exception e)
{
System.out.println(e);
}
}
}//客户端程序import java.net.*;
import java.io.*;
class clinetsocket{
public static void main(String args[]){
Socket clinetSocket;
BufferedReader br1,br2;
PrintStream ps;
String inString1,inString2;
try{
clinetSocket=new Socket("localhost",7777);
br1=new BufferedReader(new InputStreamReader(System.in));
br2=new BufferedReader(new InputStreamReader(clinetSocket.getInputStream()));
ps=new PrintStream(clinetSocket.getOutputStream());
inString1=br1.readLine();
ps.println(inString1);
inString2=br2.readLine();
System.out.println(inString2);
br1.close();
br2.close();
ps.close();
clinetSocket.close();
}
catch(Exception e)
{
System.out.println(e);
}
}
}
