java.Lang.classCastException

[Aalok Mishra]

Hi All,

I am trying to store the string list in and object array but I am getting classCastException on it. Can anyone help me on that?
I am using JDK1.5.

Here is the code:

 

List<List><String>> statusResultList = new ArrayList<List><String>>();
			
			for (int b = 0; b < statusQueryResults.size(); b++)
			{
				Object[] statusRow = statusQueryResults.get(b);
                                                                 /**
                                                                   Some code
                                                                    */
                                                 }

The statusResoultList has data in it hence for loop is getting called but at the ddeclaration part of statusRow I am gettign the exception.
Please help me as soon as possible!!

No idea why you get a ClassCastException, we don't know what's in statusQueryResults. In fact, we don't even know its actual type. I'm guessing it's List<Object[]>.

Can you show us the pieces of code where you add data to it?

Please help me as soon as possible!!

hi,

First Thing, sorry for the asap part.I'll take care abt it in furture.

Now, to anwer your question,sure I can. Here is the piece of code that is populating data in the statusQueryResult.

   

List<Object[]> statusQueryResults = getTimesheetPM().getResourceSubmitTimesheetsStatus(weekId);

 

This code return all the columns in the table for the week id provied. The status QueryResults is gettign populatedd correctly as I have debugged it till taht point. But I ma not able to debug this calssCastException.

Hi Aalok

Looking at your code I can't see anything in particular that would be causing a class cast exception.
Could you please check the stack trace to find out which line number the error was flagged on, and then double check that it does fall on the line you think it does (I assum you think this is 'Object[] statusRow...').
Also was there any reason you included 'statusResultList' at the beginning of your first code snippet? The reason I ask is that doesn't get used anywhere so wondered why it had been included
