What is the difference between JSP and Servlet in Java EE?

JavaServer Pages (JSP) and Servlet are both key components of Java EE for developing web applications. While they both serve a similar purpose of generating dynamic web content, there are some differences between the two:

1. Programming Model: Servlets follow a more programmatic approach where the logic and presentation layers are tightly coupled, while JSP allows for a more template-based approach where the HTML markup and Java code can be separated.
2. Code Complexity: Servlets tend to have more complex code as they require writing Java code to generate HTML content, whereas JSP allows embedding Java code within HTML markup, making it more intuitive for web designers.
3. Page Design: With JSP, designers can work on the visual aspects of the web page using HTML and CSS, while developers can focus on the business logic. Servlets, on the other hand, require developers to handle both presentation and logic in Java code.
4. Compilation Process: JSP pages are compiled into servlets before they can be executed by the web container, while servlets are compiled directly into Java bytecode.
5. Performance: Servlets are generally considered to be more efficient in terms of performance as they directly generate output without any additional translation steps, whereas JSP pages may incur a slight overhead due to the compilation process.

Understanding these differences can help you choose the appropriate technology based on the specific requirements of your Java EE project.
