server.java

利用Socket编程制作一个简单的C/S应用。其中

import java.net.*;
import java.io.*;

public class server{
        public static void main(String args[]){
                ServerSocket s=null;
                Socket s1;
                OutputStream sout;
                InputStream sin;
                DataOutputStream dos;
                DataInputStream dis;
                float a1,a2,he; 
 
                try{
                    s=new ServerSocket(8305);
                }
                catch(IOException e){}
                while(true){
                    try{
                         s1=s.accept();
                         sin=s1.getInputStream();
                         dis=new DataInputStream(sin);              
                         a1=dis.readFloat();
                         a2=dis.readFloat();
                         he=a1+a2;
                         sout=s1.getOutputStream();
                         dos=new DataOutputStream(sout); 
                         dos.writeFloat(he);
                         dos.close();
                         dis.close();
                         sout.close();
                         sin.close();
                         s1.close();
                    }
                    catch(IOException e){}
                }
         }
}
