SOCKET PROGRAMMING IN JAVA

SIMPLE CLIENT AND SERVER PROGRAMMING USING SOCKETS IN JAVA

         Server socket:

    import java.net.ServerSocket;

   import java.net.Socket;

                      ServerSocket ss=new ServerSocket(6655);

                       jLabel1.setText("SERVER STARTED....");

                        Socket s=ss.accept(); //WAIT TILL CONNECTION RECEIVED FROM CLIENT..

                        jLabel1.setText("SERVER CONNTECTED WITH CLIENT....");

                        DataInputStream dis=Input();

                        DataOutputStream dout=output();

                       String type=dis.readUTF();

                    System.out.Println(type);

      public  DataInputStream Input() throws IOException

    {

        DataInputStream dis=new DataInputStream(s.getInputStream());

        return dis;

       

    }

    public  DataOutputStream output() throws IOException

    {

        DataOutputStream dout=new DataOutputStream(s.getOutputStream());

        return dout;

       

    }

CLIENT SOCKET:-

Streams.java

import java.io.DataInputStream;

import java.io.DataOutputStream;

import java.io.IOException;

import java.net.Socket;

public class Streams

{

    //Socket s;

    public DataInputStream Input(Socket s) throws IOException

    {

        DataInputStream dis=new DataInputStream(s.getInputStream());

        return dis;

       

    }

    public DataOutputStream output(Socket s) throws IOException

    {

        DataOutputStream dout=new DataOutputStream(s.getOutputStream());

        return dout;

       

    }

}

USING STREAMS IN NATIVE CODE:

NativecodecLIENT.java

import java.io.DataInputStream;

import java.io.DataOutputStream;

import java.io.IOException;

import java.net.Socket;

String host=”localhost”;

   Socket s =new Socket(host,6655);//ESTABLISH CONNECTION TO SERVER WITH IP 127.0.0.0.1

     DataInputStream    dis=new Streams().Input(s);

        DataOutputStream    dout=new Streams().output(s);

          dout.writeUTF("data variable 1");
