What is the difference between JSP and Servlets, and when would you choose to use one over the other in a Java web application?

Difference Between JSP and Servlets in Java Web Applications

The main difference between JSP (JavaServer Pages) and Servlets in Java web applications lies in their primary roles and functionalities. Servlets are Java classes that handle the request-response cycle on the server-side, providing dynamic and customized responses based on the client's request. On the other hand, JSP is a technology that simplifies the process of creating dynamic web pages by embedding Java code within HTML.

When to Choose Servlets:

If the web application requires complex business logic, processing of forms, database operations, or handling of low-level HTTP requests and responses, Servlets are the preferred choice. Servlets offer more control and flexibility in managing the server-side logic of the application.

When to Choose JSP:

When the focus is on creating dynamic web pages with minimal Java code and a visually appealing frontend, JSP is the ideal option. JSP allows for easy integration of Java code into HTML, making it suitable for rapid development of web interfaces that require a combination of static content and dynamic data.

Both Servlets and JSP are essential components in Java web development, and the choice between them depends on the specific requirements of the application. By leveraging the strengths of each technology, developers can build robust and user-friendly web applications that meet the desired objectives.
