What is the difference between a JSP and a servlet?

**

In the world of Java web development, understanding the difference between a JSP (JavaServer Pages) and a servlet is essential.

JavaServer Pages (JSP)

**
A JSP is essentially an HTML page with embedded Java code. It allows for the dynamic generation of web content by enabling developers to write Java code directly within the HTML page. JSP pages are compiled into servlets before being run, making them efficient for generating dynamic content.

**

Servlet

**
In contrast, a servlet is a Java programming class that handles HTTP requests and generates responses dynamically. Servlets are the fundamental building blocks of Java web applications and are responsible for processing requests and generating responses. Unlike JSP, servlets do not have HTML code embedded within them.

**

Differences:

**
1. **Structure:** JSP allows developers to mix Java code with HTML, while servlets involve writing Java code to handle HTTP requests and responses without embedding HTML.
2. **Ease of Use:** JSP is generally considered easier to work with for web developers as it resembles HTML and allows for easy integration of Java code.
3. **Reusability:** Servlets are more reusable as they separate business logic from presentation logic, making them more suitable for complex web applications.
4. **Performance:** Servlets are often faster and more efficient than JSP pages, as servlets are precompiled into Java bytecode.

In summary, while both JSP and servlets play crucial roles in Java web development, their differences lie in their structure, ease of use, reusability, and performance.

By understanding the distinction between JSP and servlets, developers can leverage the strengths of each technology to build robust and efficient Java web applications.
