Creating Streams

• The following code shows how you might create a stream to talk to another machine.

//Read and write some text
Socket a_socket = new Socket(www.sc.edu, 80);
InputStreamReader isr = new InputStreamReader(a_socket.getInputStream());
BufferedReader in = new BufferedReader (isr);
PrinterWriter out = new PrinterWriter(a_socket.getOutputStream()); 

//Read and write some binary data
Socket socket_data = new Socket(www.sc.edu, 100);
DataInputStream in_data = new DataInputStream(Socket_data.getInputStream());
DataOutputStream out_data = new DataOutputStream(socket_data.getOutputStream());

• The Streams provide byte-by-byte data. The Reader and Writers transform these bytes to characters.
