There are three ways to develop
1. Take Java class implementing javax.servlet.Servlet(Interface) and provide implementation to all the 5 methods of that interface
2. Take a java class extending from javax. servlet.GenericServlet(class) and provide implementation to public void service(-,-) method.
3. Take a Java class extending from javax.servlet.HttpServlet(class) and override one of the seven (7) doXXX(-,-) methods.
How many types of servlets?

GenericServlet is the super class contains common properties and logics.

I am glad you take pride in what you write. This makes you stand way out from many other writers that push poorly written content. blockchain fullstack developers
