java socket programming example
In the era of network programming means write such a script
that can be executed on multiple computers / platform. In J2SE, a package
java.net provide the number of API that can be used to write code for the
communication between multiple computers / platforms. The java.net package of
J2SE provide the sport for two important protocol of the network that is TCP
and UDP.
The Socket in java provide the way of communication between
two or more computers using Transmission Control Protocol (TCP). Here we have socket on
both side at Client as well as server. A client socket try to communicate to
server socket. If everything is fine server accept the connection and
communication process begin.
Here I am going to demonstrate a simple example of server socket programming. I have created a java package bsr and my class that have the definition of socket MySocket.java is placed inside this package.
I have also created two more class to simulate the behavior of client and server namely sender and receiver. I used plain text editor to create my script.
