public class LifeCycle extends HttpServlet {

public static int instanceCount;
{
System.out.println("Doing static initialization on LifeCycle class");
instanceCount = 0;

}

public void init() {
System.out.println("In init() on LifeCycle");
}

public LifeCycle() {
instanceCount++;
System.out.println("In LifeCycle constructor");
}

public void destroy() {
System.out.println("In destroy() on LifeCycle");
}

public void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
System.out.println("In doGet() on LifeCycle");
try {
throw new Exception();
} catch (Exception e) {
// Just doing this to show doGet() called from service()
e.printStackTrace();
}
}

}

i have written the following program which basically demonstrates Servelt life cycle.

i worked it in a notepad.

class neeti {

static int year[]; /*****************8DOUBT*********/

public static void main(String args[]) {
System.out.println(year);
}
}

/********** doubt*********************/

is there a object reference there --- the DOUBT line...or is it a primitive?

it is said that without the strictfp modifier floating points used in methods behave in platform dependent way..

how come it is true??
because java is platform independent right??

Hi Mark,

thisObject.compareTo(anotherObject)

you mean to say thisobject and anotherObject always will have different values?

for EXAMPLE:

Birthday girl/Thriller/Nicole kidman
Original Sin/adventure/Angelina Jolie
Evil Dead/Horror/Campbell

so suppose thisObject value is Birthday Girl so the value of anotherObject can never be Birthday Girl is it? it has to be either Original Sin or Evil Dead right?

Then when does comparator come into picture? is it that it compares Instance by Instance?

Suppose for first value of DVDInfo d the value is

Birthday girl/Thriller/Nicole kidman

so d.getTitle() will return Birthday girl and
return title.comapreTo(d.getTitle());
title will also contain Birthday girl then its the same right??

i didnt understand the concept of
thisObject.compareTo(anotherObject)

here what is thisObject and what is anotherObject?
i mean are both BIRTHDAY GIRL??

public int compareTO(DVDInfo d) {

return title.comapreTo(d.getTitle());
}



suppose for example we have

Birthday girl/Thriller/Nicole kidman
Original Sin/adventure/Angelina Jolie
Evil Dead/Horror/Campbell


what is the difference between title and d.getTitle , i guess both will have same objects. i want to understand how are the objects taken???\

can anyone help?
