Micro Project Proposal
CHAT APPLICATION IN JAVA USING
(CLIENT & SERVER SOCKETS)

1.0 Brief Introduction

Several network systems are built to communicate with one another and are made available
through service-oriented architectures. In this project, we use the client-server architecture to
develop a secured Client-Server chat application. A chat application is created based on
Transmission Control Protocol (TCP) where TCP is a connection-oriented protocol and in the
end, multithreading is used to develop the application.

A client-server chat application consists of a Chat Client and a Chat Server and there exists a
two-way communication between them. Here, the Message Processor is used to interpret the
message from the user, Message Interpreter is used to extract and pass the received message.
Message Maker is used to construct back the message and Client Manager is used to maintain
the clients list which the sender and receiver on both sides use to interact with each other.

2.0 Aim of Micro project

1. To study various concepts of Java.
2. To understand the need for sockets in chatting applications.
3. To study various types of socket.

CHAT APPLICATION IN JAVA USING
(CLIENT & SERVER SOCKETS)

1.0 Brief Introduction

A chat application in Java using client and server sockets allows two or more users to
communicate over a network in real time. It typically involves a server socket that listens
for incoming connections from clients and manages the communication between them.
The client socket connects to the server and exchanges messages by sending and
receiving data. The server can broadcast messages to all connected clients or relay
messages between them. This setup demonstrates basic networking concepts in Java,
such as multithreading (to handle multiple clients) and input/output streams for message
transmission. It is commonly used in learning how to build real-time communication
systems.
In general, the server process will start on some computer system; in fact, the server
should be executed before the client. The server usually initializes itself and then goes to
the wait state or sleep state where it will wait for a client request. After that, a client
process can start on either the same machine or on some other machine.. This process is
repeated as long as the server processes is running. Whenever such a request comes, the
server can immediately serve the client and again go back to the waiting state for the next
request to arrive.

9.0 Conclusion & Future Scope:

In conclusion, a chat application in Java using client and server sockets
provides a practical and foundational approach to understanding network
communication. It demonstrates how Java's socket programming enables real-
time data exchange between multiple clients and a server. By employing
multithreading and input/output streams, the application showcases key concepts
such as concurrency and message handling. This project is an excellent way to
grasp the basics of network programming, scalability, and real-time
communication, forming a strong foundation for more complex distributed
systems.
