Hi Tirumala Raju,

It is a good programming practice to include the braces even for a single statement inside a loop .
Hope this clears your confusion.

Thanks,
Kishore

Instance methods are those invoked by object;
conventionally instance methods are refered to as normal methods;
Hope you got some clue

Hi,

Currently , I'm dealing with pagination .
I'm tryiing to do it by query.
but,i'm n't successful.
Pls. help me.

code:
______

My query is:
String query = "Select * from (Select a.*, rownum rnum From (select * from "
+ TableDetails
+ " order by rowid desc)a where rownum <= "
+ (recordsPerPage * (Integer.parseInt(pageNumber)))
+ ") where rnum >"
+ (recordsPerPage * ((Integer.parseInt(pageNumber) - 1)))
+ "";

with this query,
I'm not able to get all the results.
I'm missing some records.(say, missing 2 of 6)
I mean, this is working fine for Next button in jsp , but not for Previous button.

How can i modify the query?


Pls help me.


Thanks,
Kishore

Hi ShivaMohan,
That was a very nice question indeed.
The explanation is also good:

"This is because, after a call to super() in the Parent constructor, the instance variable initializers and instance initializers will execute. This will cause assignment of "Parent" to the instance variable s. Only after this will the call to method() within the constructor execute."

It means, only after completely executing initializers ,the control returns to sub class constructor

Hi Suresh,
The prog results in compile time error.
