Discover the Truth of Servlets!

Servlets are a key component of Java web applications, but many people don't know what they are or how they work. So which of the following is true about servlets? Let's find out!

What is a Servlet?

A servlet is a small Java program that runs on a web server and processes requests from web browsers. Servlets are used to handle a variety of tasks, from processing HTML forms to generating dynamic web content. They are part of the Java EE (Enterprise Edition) platform, which is used to create large-scale web applications.

How Servlets Work

Servlets are written in Java and compiled into bytecode, which is then loaded into a web server. When a web browser requests a servlet, the web server calls the servlet's service() method, which is responsible for processing the request and sending a response back to the web browser. The service() method can use various Java APIs to generate dynamic web content, as well as connect to databases and other external services.

What Servlets Can Do

Servlets are often used to process HTML forms. When a web browser submits a form, the web server calls the servlet's service() method and passes it the form data. The servlet can then use the form data to perform some kind of action, such as saving the form data to a database or sending an email. Servlets can also be used to generate dynamic web content, such as HTML pages or XML documents.

Advantages of Using Servlets

Servlets are fast, reliable, and scalable. They are also easy to develop and maintain, since they are written in Java and can use the Java APIs. Additionally, servlets are platform-independent, meaning they can run on any operating system with a Java Virtual Machine.

Conclusion

Servlets are an integral part of Java-based web applications. They are used to process requests from web browsers and generate dynamic web content. Now you know which of the following is true about servlets: they are small Java programs that run on a web server and can be used to process HTML forms, save form data to a database, and generate dynamic web content.
