Creating a picture in java out of a txt file containing 0's and 1's

[The Dark Dragon]

I need to make a 2D array out of the 0's and 1's in the file. The file is 25X25 in total so contains 625 characters in all, either 0 or 1.

This is the code I have so far:


import london.*;
public class Picture {
public static void main (String[] arg) {
EasyReader fileInput = new EasyReader("picture.txt");
EasyGraphics g = new EasyGraphics(30,30);

int cols = 30; // How many columns the array should have
int rows = 30; // How many rows the array should have

int[][] array2d = new int[rows][cols];

String strLine;
int xCounter = 0;
// Reading lines from the file using EasyReader
while ((strLine = fileInput.readLine()) != null) // fileInput.readLine() fills the variable strLine with a String value.
{
char[] stringArray= new char[42];
stringArray = strLine.toCharArray();
//display the array
for(int index=0; index < stringArray.length; index++) {
array2d[xcounter][index] = (int) stringArray[index] - 0x30;
}
xCounter++;
}
}
}


The EasyReader is just a class for input that inherits the BufferedReader class and is part of the "london" package. There is 1 error in compilation which says:


Picture.java:21: cannot find symbol
symbol : variable xcounter
location: class Picture
array2d[xcounter][index] = (int) stringArray[index] - 0x30;
^


Please can someone help me, I am literally pulling my hair out at this!

xcounter != xCounter

Please note: the compiler is very unforgiving.
