Hi,
I am creating a project as part of a University Assignment and all was well until i encountered a dreaded NullPointerException! I have tried all i can to work a way around it but just can't seem to suss it out. It has been causing me endless hours of frustration! If anyone could help me out then it would be HUGELY appreciated! I have included my code below and the error seems to be occuring on line 210 which reads:
if (stockCode[itemNum].equals(searchItem))
My Code
-------

[JAM -->Edited to use [CODE] and [/CODE] tags]

It looks like your problem is in readData()
int count=0;
...
...
do
{
count++;//<---------------count is now 1, meaning stockCode[0] is null
stockCode[count] = input.readLine();
move the count++ to the end of the do/while block

Hi again,
Solved it by changing the problamatic line 210 to
CODE] if (stockCode[itemNum]!=null && stockCode[itemNum].equalsIgnoreCase(searchItem))[ [/CODE]
Also implemented your idea, much more sensible that putting it before !
Thanks for your help, i sure i'll be back asking for more very shortly!
Thanks again,
Emile

I can't speak for your teacher, but where I went to school we'd lose points for not indenting. It's hard to follow your logic otherwise.

It's not that the code wasn't indented; it's that the [CODE] and [/CODE] tags were not used; thus, the indenting was not preserved. I edited the post to include them this time....
