Ok, that made the original error go away and I think I understand why.
Seems like NetBeans is tying to make me write fault tolerant code, jerk.
However I have a new error that I don't understand. The sirLine = new...
line gives me:
cannot find symbol
symbol : variable fs
location: class hockey_pool.Main
I have googled for this and cannot find what this means. I thought that it
meant that I have not defined a variable, but I have in the line in the
try{}. So, what am I missing here?
The problem is that you declared it in the try block. It's the same
problem as you would have if you declared a variable in an if block
and then tried to use it outside of that block.
The first thing I'd try to fix this is to put all the code that depends
on fs into the try block.
Thanks Monique. I surrounded all of the relevent code with the try block
which then resulted in another error, which was an IOException. Rinse and
repeat. I got it working now but I have a few nested try blocks. Is that
normal?
try{
FileInputStream fs = new FileInputStream(f);
InputStreamReader sirLine;
BufferedReader fileInput;
sirLine = new InputStreamReader(fs);
try{
fileInput = new BufferedReader(sirLine);
//MY WICKED AWESOME CODE HERE
}
catch(IOException IOE){
System.err.println("Something is awry!");
}
}
catch(FileNotFoundException fnfE){
System.err.println("File not found!");
}
Of course with the apropriately nested catch statements. Is there a
cleaner way to do this?
Thanks for the help,
