In order for someone to be able to help you, you are going to need to post the code. Just providing the error message that you are getting does provide enough insight into why you are getting this error message.

Hi,

I am attaching the code

First of all, this is a beginner topic and I've marked it as such. Second, I've closed your other duplicate topics (there were two!). It's against the rules to make duplicate posts. Plus it's annoying, and will not get you help any faster. Third, you didn't attach any code, but lucky for you the stack trace is very easy to read:



The first line tells you that it's a NumberFormatException. The second line tells you where it happened: at java.lang.Integer.parseInt(Integer.java:435). You are trying to call parseInt on a value that cannot be turned into an integer. Put a breakpoint before this line and run a debugger to see what you are trying to pass into that method. If you don't know how to use a debugger, print the value out to the console (std out) to see what you are passing to the parseInt method. Here's an example of different values that you might pass to parseInt and their results


int y = Integer.parseInt(x); // x is a String

if x == "5" then y == 5

if x == " 5" then NumberFormatException is thrown
There's an extra space, which can't be converted to a number

if x == "#" then NumberFormatException is thrown
How can you convert "#" to a number?

Hello,

Have you read my query till end.because after fetching some number of rows I am getting the error "TOO MANY FILES OPEN".

I can trace the other part.Just want the info about TOO MANY FILES OPEN Error ,even I have closed all opened files

just post the code inside of [code] blocks and we can help you out a lot easier... also sometimes fixing some of the small errors also eliminates the large ones.
