java--Server

Open the server and open 9000 ports:

ServerSocket serversocket=new ServerSocket (9000);

A listening port that, if a client connects to the server, encapsulates the client data as a socket object:

Socket socket=serversocket.accept ();

Get the read stream from the socket for receiving data:

InputStream In=socket.getinputsream ();

Get the write stream from the socket for sending data:

OutputStream Out=socket.getoutsream ();

Reads the resulting data into a byte array:

Byte[] B=new byte[1024];

In.read (b);

Encapsulates the data of a byte array into a string:

String S=new string (b). Trim (); Remove both spaces

Send data to the client:

Out.write ("Hello". GetBytes ());

Refresh the stream;

Out.flush;

Close the stream;---first established and then closed

In.close ();

Out.close ();
