There is an input-output stream that is used to read and write messages over the network. It works like sending and receiving messages and forwarding them to the right place. We are going to make a Server.java file that handles all the methods and is constructed to make a functional server side. This uses a socket to communicate through the client’s IP address and access port number. Server Side java programming that listens for incoming connections on a specific port and sends a message back to the client when a connection is maintained. Just choose java and create a file and run the program. You can simply run all the code in the codedamn playground i.e online IDE for Java programming which doesn’t require you to download or set up any sort of stuff. To develop or make one server-side program in java you first need to install and set up the java environment which includes Java Development Kit (JDK) and one IDE such as Eclipse or IntelliJ.īut for this java chat application, you don’t need to have Eclipse or even VScode. These technologies handle and maintain the HTTP request from the client and generate dynamic content. In java, server-side programming is typically implemented using java socket or using java servlets. These programs are usually responsible for handling requests from clients, performing server tasks like data fetching, and handling the request of a client. Server-side programming is a way to develop an application that should run on a server and should be accessible by the client over any network. What is server-side programming? Server-side Programming The last Client.java represents the front-end part and how the client will work. This chat application will consist of three files Server.java represents the backend of the chat application and act as a provider, next is ClientHandler.java which implements thread and each message gets concurrently executed with the help of thread and it handles all the thread functionalities. The most simple way is to use Java Socket Class and Thread Class to create client-server architecture, where the server represents the back end of the chat application and the client represents the front end of the chat application. To develop a chat application in java there are various methods or ways that one can develop the application. Chat applications can be used for various purposes such as connecting with friends and using the application for business inquiries. It can run multiple client-server chats easily. Where the messages are getting exchanged in real-time. Chat applications allow users to communicate with each other that should be in real-time. Java chat applications are developed using the java programming language. What is java chat applications? Java chat And after this, you can implement a socket with a socket class, which takes two inputs in the form of an IP address and port number. To implement threads in socket programming in java we can use the Thread class and then override the run method. Using a thread can be very useful while sending and receiving data on a socket, or performing other operations while it’s waiting for data. This makes it easy to work and perform complex and multiple operations along with the socket. Thread can be used to allow multiple tasks to be performed simultaneously in a single program. It separates the execution flow and this separation gets executed simultaneously with other threads that are present in the same program. ![]() While threads allow a program to perform multiple tasks simultaneously, rather than executing them one by one. It works as a client-server method where the client sends the request to the server and the server responds to the client with the requested data. Socket programming is used to work with sockets which helps in making a network connection to the server. Introducing threads in socket programming If you are new to Java so check out the codedamn course for Java that covers all the fundamentals and takes you from beginner to master in Java programming you should take this before starting the chat program in java. This article assumes that you already know the fundamental of java and has a basic understanding of socket which covers socket programming and a little bit of knowledge about the client-server model. In this article, we are going to make a java chat application that will work on multiple client sockets and create a working chat program in java. ![]() Java provides many features to make complex things easy. When it comes to programming Java always remains at the top of developing complex applications because of the ecosystem Java has.
