first of all, you forgot to use code tags, which makes this very difficult to read
I sujest you check the line where the exception occurs, check whether or not you've forgotten a test on it and if you still can't find it, put your code back here in a readable way

code tags, clear distinctions between the different .java files, ...

Hi VirusTalker,

Your code seems Ok. However, in the printContents(BufferedReader in) method, after tokenizing the read string from file, try checking if it hasMoreTokens.

Look at the below modified code of your method and try if it works. Hope it does;

private static void printContents(BufferedReader in)
{
double[][] a = new double[MAX_UNKNOWNS][MAX_UNKNOWNS+1];
int i,j;

int numUnknowns = 0;

try{
String line = in.readLine();

while(line != null && line.length() > 0)
{

// read number of unknowns
numUnknowns = Integer.parseInt(line);

// print out unkowns
System.out.println("\nNumber of unknowns: " + numUnknowns);

// read in equations
for(i=0;i 0)System.out.print(" + ");
System.out.print(a[i][j] + "x_" + (j+1));
}

a[i][j] = Double.parseDouble((tok.nextToken()));
System.out.println(" = " + a[i][j]);
}
}

gaussian(a, numUnknowns);

line = in.readLine();
} // end while

} // end try

catch (IOException e)
{
System.out.println("I/O Error");
System.exit(0);
}

catch(NumberFormatException ex)
{
System.out.println("Impropper number encountered in file");
System.exit(0);

}

}

Its working fine, with no exceptions.
