Java is one of the most used programming languages for developing dynamic web applications. A web application is computer software that utilizes the web browser and technologies to perform tasks over the internet. A web application is deployed on a web server.
Java provides some technologies like Servlet and JSP that allow us to develop and deploy a web application on a server easily. It also provides some frameworks such as Spring, Spring Boot that simplify the work and provide an efficient way to develop a web application. They reduce the effort of the developer.
We can create a website using static HTML pages and style them using CSS, but we need server-side technology when we want to create a dynamic website.
In this section, we will see how to create a website using Java Servlets and HTML. Further, we will see how these technologies are useful for developing a web application.

Let's understand the components of a web application:
What is a Web Application
A web application is computer software that can be accessed using any web browser. Usually, the frontend of a web application is created using the scripting languages such as HTML, CSS, and JavaScript, supported by almost all web browsers. In contrast, the backend is created by any of the programming languages such as Java, Python, Php, etc., and databases. Unlike the mobile application, there is no specific tool for developing web applications; we can use any of the supported IDE for developing the web application.
Web Server and Client
The web server is a process that handles the client's request and responds. It processes the request made by the client by using the related protocols. The main function of the webserver is to store the request and respond to them with web pages. It is a medium between client and server. For example, Apache is a leading webserver.
A client is a software that allows users to request and assist them in communicating with the server. The web browsers are the clients in a web application; some leading clients are Google Chrome, Firefox, Safari, Internet Explorer, etc.
HTML and HTTP
The HTML stands for HyperText Markup Language; it is a common language for Web Server and Web Client communication. Since both the web server and web client are two different software components of the web, we need a language that communicates between them.
The HTTP stands for HyperText Transfer Protocol; it is a communication protocol between the client and the server. It runs on top of the TCP/IP protocol.
