Java Servlets
Java Servlets are server-side Java programs that extend the capabilities of web servers to generate dynamic web content. They handle HTTP requests and responses, enabling the creation of interactive web applications by processing data, managing sessions, and interacting with databases. Servlets run within a servlet container like Apache Tomcat, providing a robust foundation for Java-based web development.
Developers should learn Java Servlets when building enterprise-level web applications in Java, as they form the core of the Java EE (now Jakarta EE) web stack and are essential for understanding frameworks like Spring MVC. They are particularly useful for handling complex business logic, secure transactions, and scalable server-side processing in environments requiring high performance and reliability, such as banking or e-commerce systems.
