JSP (JavaServer Pages) and Servlets are complementary technologies for creating dynamic web pages using Java. While Servlets provide the foundation, JSPs make development easier by enabling standard HTML pages with Java tags, separating presentation from business logic. For example, a JSP page can contain a form that submits user input to Java code, which then outputs the values. Key advantages of JSPs over other methods are the separation of dynamic and static content for simpler development and maintenance, as well as platform independence since JSPs produce HTML and run on any server using Java.
