Servlet writing

Java. servlet package and Java. servlet. http package provide interfaces and classes to write servlet. All Servlet classes must implement the servlet interface. Here, Sun has compiled an httpservlet class, which is an abstract class that implements the servlet interface. When writing the servlet class, we can inherit the methods required to implement the httpservlet class.

Public class myservlet extends httpservlet {@ override protected void doget (httpservletrequest request, httpservletresponse response) throws servletexception, ioexception {... } @ Override protected void dopost (httpservletrequest request, httpservletresponse response) throws servletexception, ioexception {... } @ Override Public String getservletinfo () {return "Short Description ";}}
