Having trouble with reading hex from an input file - please help

Question

Hi, I have a txt file with rows of hex, and I need to read each line and add it to an int array. So far I have:
BufferedReader fileIn = new BufferedReader(new FileReader("memory.txt"));
                int count = 0 ;
                String temp = fileIn.readLine();
                int file_in = Integer.parseInt(temp) ;
                while(temp!=null) {
                     data[count] = file_in;
                     temp = fileIn.readLine();
                     file_in = Integer.parseInt(temp,16);// Integer.parseInt() ;
                     count++ ; /* increment counter */
                } memory.txt:
4004000
4008000
3FDF4018
4108200
3C104001
FFFFFFE8
4010C6C0
FFFFFFE8
94000000The above code crashes on the third input (my guess is becuase there are letters in and it can't parseInt letters.
I think I need to parse it into an array of chars instead, however I don't know how to get from the string (temp) to the char array.
can anyone help?

Answer 1

ok turns out it's just a null pointer exception on the data[count] line, becuase I've only initialised the first two slots of data. i didn't see it before becase it was just throwing an error and i never printed it out.
here's how I've defined data:
in the class
int[] data;just before the code to input the file data:
for ( int i = 0; i < length; i++ )       
                data [ i ] = 0;thinking this shoudl go through all the array and initialise it. but it gives a NullPointerException on the data=0; line.
any ideas?
