This lab will guide you to develop a simple TCP-based chat application in Java. By the end of this lab, you should have an understanding of Java network programming, thread usage, and GUI creation.
Prerequisites
Before proceeding with this lab guide, you must have a basic understanding of:
Java Programming
Basics of Networking
Java Swing for GUI (optional, since the GUI part is explained)
Lab Components
This lab consists of the following components:
Java Chat Server - A server program that can accept connections from multiple clients.
Java Chat Client - A client program with GUI that users can use to send and receive messages.
Please follow the steps provided for each component.
In this ChatServer class, the server is started on the specified port, and it keeps listening for incoming connections. When a client connects, the server adds the client's socket to its client list and creates a new thread to handle communication with that client.
The ClientHandler class extends Thread and handles communication with a client. It reads incoming messages from the client and then broadcasts them to all connected clients.
The ChatClient class is the GUI-based chat client. It establishes a connection to the server and starts a new thread to receive incoming messages. It also has a text field and a button for sending messages.
This program provides a basic example of how to create a TCP-based chat application in Java. It covers key concepts such as network programming, threads, and GUI creation in Java. Please feel free to modify and improve this example to better suit your needs and help you understand these concepts further.
