Hi malli,
GenericServlet is the super class of HttpServlet calss
java soft implemented Servlet and ServletConfig interface for developing GenericServlet.

And also keeping the needs of internet users in view,
They hav developed HttpServlet class implementing same interfaces (Servlet and ServletConfig)

HttpServlet is specific to the HTTP protocal

so any company can develop another class extending GenericServlet class

for example
XxxpServlet is specific to the Xxxp protocal
YyypServlet is specific to the Yyyp protocal

.......

Thank u
