Java 2: Networking

This course provides an overview of TCP/IP. It also describes the terms port, socket, proxy server, UDP and datagrams. The course explains the importance of the InetAddress class in Java networking. You will learn to use the methods of this class in a Java program. In addition, you will be introduced to URLs and URL related classes in Java. This course explains how to use the methods of the Socket, ServerSocket, DatagramSocket, and DatagramPacket classes in a program. You will also learn how to create TCP/IP server and clients by using sockets and datagrams. Finally the course explains how to multicast datagram packets to multiple clients.

Networking training covers such topics as:

Networking Basics
Programming Using Sockets
Programming Using Datagrams

Learn exactly what you need to know about the client/server architecture in the context of networking. You will be able to create and parse a URL, to explain the use of the InteAddress class and its methods, and to explain the methods of the URL class and the URLConnection class. You will learn about the methods of the Socket class, the DatagramPacket class, the DatagramSocket class, and the MulticastSocket class.

This course addresses the requirements of application developers and Web designers who need to design and develop applications and applets by using Java. The course prepares the learner for the Sun Certified Programmers for the Java 2 Platform - Exam #310-025.
