For another example, we could wrap the InputStream with a BufferedReader, via an InputStreamReader, in order to easily read text with methods like readLine(). For example, we could wrap the OutputStream with a PrintStream so that we can easily write text with methods like println(). OutputStream out = socket.getOutputStream() īecause these are ordinary streams, the same streams that we would use to read from and write to a file, we can convert them to the form that best serves our use case. We can execute the following methods to obtain input and output streams: InputStream in = socket.getInputStream() Input streams are used to read data from the server while output streams are used to write data to the server. Once our socket instance is connected to the server we can start obtaining input and output streams to the sever.

The following code opens a connection to a server: Socket socket = new Socket( server, port ) In implementations prior to NIO, Java TCP client socket code is handled by the class. I present a series of client-server examples that demonstrate features from the original Java I/O framework, then gradually advance to using features introduced in NIO.2. In this tutorial, I introduce you to socket programming in Java. Because TCP guarantees delivery, it is the protocol of choice for HTTP, FTP, SMTP, POP3, and so forth.

Would you prefer that the client slow down your movie to receive the missing frames or would you prefer that the video continue playing? Video streaming protocols typically leverage UDP. To appreciate the difference between TCP and UDP, consider what would happen if you were streaming video from your favorite website and it dropped frames.

UDP is a connectionless protocol and is good for scenarios where you do not necessarily need every packet to arrive at its destination, such as media streaming.In TCP, each entity knows that its communication payloads have been received.

TCP is relatively simple and reliable protocol that enables a client to make a connection to a server and the two systems to communicate.

TCP and UDP are used for different purposes and both have unique constraints: Generally, network communication comes in two flavors: Transport Control Protocol (TCP) and User Datagram Protocol (UDP). Socket programming boils down to two systems communicating with one another. Finally, you'll see an example that demonstrates Java networking as implemented from Java 7 forward, in NIO.2. You'll be introduced to both the original java.io package and NIO, the non-blocking I/O ( java.nio) APIs introduced in Java 1.4. This tutorial is an introduction to socket programming in Java, starting with a simple client-server example demonstrating the basic features of Java I/O.
