Create Input Stream - Client - In Java Programming

On the client side, you can create an output stream to send information to the server socket using the class PrintStream or DataOutputStream of java.io: 

On the client side, you can use the DataInputStream class to create an input stream to receive response from the server:

  

DataInputStream input;

   try {

        input = new    DataInputStream(MyClient.getInputStream());

   }

   catch (IOException e) {

       System.out.println(e);

   } 

PrintStream output;

   try {

        output = new PrintStream(MyClient.getOutputStream()); }

   catch (IOException e) {

         System.out.println(e);

   }

The class PrintStream has methods for displaying textual representation of Java primitive data types.

you may use the DataOutputStream   DataOutputStream output;

   try {

         output = new DataOutputStream(MyClient.getOutputStream());

   }

   catch (IOException e) {

        System.out.println(e);

   }

The class DataOutputStream allows you to write Java primitive data types; many of its methods write a single Java primitive type to the output stream.

The method writeBytes is a useful one.
