Can we call destroy() method inside the init() method? What
happens when we do so?
 Question Submitted By :: Servlets
I also faced this Question!!     Answer Posted By  
# 1
In the Servlet programming context, the destroy() method
can never be called by your code and is called by the
servlet container
Is This Answer Correct ?    19 Yes 4 No
# 2
This action does not disturb the normal life cycle flow of the servlet. The servlet will work normal. You may test the below code.

* @author Suraj
public class TestServlet extends HttpServlet {

public void init(ServletConfig config)throws ServletException{

protected void doGet(HttpServletRequest req, HttpServletResponse resp)
throws ServletException, IOException {

System.out.println("I am test servlet.");


<?xml version="1.0" encoding="UTF-8"?>
<web-app id="WebApp_ID" version="2.4" xmlns="" xmlns:xsi="" xsi:schemaLocation="">
Test URL: http://<HOST>:<PORT>/<Context>/

a call to the destroy method will happen and the resources
will be released and the flow will continue as it is and
will throw an exception if the released resource is used
indie the service method call.
Is This Answer Correct ?    2 Yes 0 No
# 5
One can call destroy method from init method. One scenario
in which you would like to call is some resource is looked
up once in init() method and cleaned in destroy() method. If
exception is thrown before it finishes as servlet is not
brought in service, container won't call destroy method. so
to keep resource clean you can call destroy() method from init()
Is This Answer Correct ?    3 Yes 1 No
# 6
if suppose we take the servlet programming side then
whenever u type the URL first web browser call the service
method then create the servlet object then call the
init()method whenever we call the init method start the
proceesses of the particular object operation suppose we
call the destroy()method before completion of the particular
object operation servelet object is removed then when we r
call the service method then create the servelet object
