A Tutorial on Socket Programming in Java in pdf

We present a tutorial on socket programming in Java. This tutorial illustrates several examples on the two types of socket APIs: connectionless datagram sockets and connection-oriented stream-mode sockets. With datagram sockets, communication occurs in the form of discrete messages sent from the sender to receiver; whereas with stream-mode sockets, data is transferred using the concept of a continuous data stream flowing from a source to a destination. For both kinds of sockets, we illustrate examples for simplex (one-way) and duplex (bi-directional) communication. We also explain in detail the difference between a concurrent server and iterative server and show example programs on how to develop the two types of servers, along with an example. The last section of the tutorial describes the Multicast Socket API in Java and illustrates examples for multicast communication. We conclude by providing descriptions for several practice programming exercises that could be attempted at after reading the tutorial.
