Socket BASIC Programming

1. The server code is as follows:

 

Package COM. njupt. webService; import Java. io. bufferedreader; import Java. io. ioexception; import Java. io. inputstream; import Java. io. inputstreamreader; import java.net. serversocket; import java.net. socket; public class server {public static void main (string [] ARGs) throws exception {serversocket Ss = new serversocket (6789); While (true) {socket S = ss. accept (); inputstream is = S. getinputstream (); bufferedreader BR = new bufferedreader (New inputstreamreader (is); string STR = BR. readline (); system. out. println ("client:" + Str); BR. close (); is. close (); S. close ();}}}

 

2. The client code is as follows:

 

Package COM. njupt. webService; import Java. io. bufferedwriter; import Java. io. ioexception; import Java. io. outputstream; import Java. io. outputstreamwriter; import java.net. socket; import java.net. unknownhostexception; public class client {public static void main (string [] ARGs) throws exception {socket S = new socket ("127.0.0.1", 6789); outputstream OS = S. getoutputstream (); bufferedwriter BW = new bufferedwrite R (New outputstreamwriter (OS); BW. Write ("do I like Zhang Zetian? "); BW. Close (); OS. Close (); S. Close ();}}
