Help with line count

10 New Member
Hi, I am having problems with this bit of code:

public class main

public class readAccounts
reader1 r = new reader1();


void readAccounts()
printFile("acco unt.txt");
static void printFile(Strin g fileName)
System.out.prin tln();

String[] lines = LineIO.readAllL ines(fileName);
for (String l : lines)

System.out.prin tln(l);
public static void main(String[] args)
for (String arg : args)
// print number of lines

private static void count(String name)
long numLines = 0;
String lines;
do {
lines = LineIO.readAllL ines(fileName);
if (lines != null)

while (line != null);
System.out.prin tln(numLines)


The basic function is to read a text document then display the document with the amount of lines in the text file. So far it works fine if the print lines code is taken out. It will display the text document perfectly. However when the new code is added I get an error message saying that 'cannot find symbol = variable file name'

Im sure this is simple to rectify and any help would be welcomed

in your count method, you pass in a String called name, and then try to readAll fileName, you might like to change one of them.

What is the while loop doing down the bottom? (it loops while line!=null BUT I don't think it can see line (in which case it won't run), nor is line being modified (so it will run forever), and finally it has a semi-colon behind it (so it won't do aything). Are you trying to run multiple threads or something (or did this accidently slip in).....?

Sorry, the do...while structure caught me out - nonetheless I think it should be lines not line......(you can ignore the rest of what I said...I wasn't looking properly.

When posting code please use code tags so that your code is readable.

This method will not compile because you are using the variable fileName which is neither declared nor passed into the method.

  1.  private static void count(String name) { 
  2.  long numLines = 0;
  3.  String lines;
  4.  do {
  5.    lines = LineIO.readAllLines(fileName);  //fileName is unknown here

  10.  while (line != null);

I have compiled some code, some written by me, some compiled from various sources online, and basically i've got a very simple flat file photo gallery. An upload form, to upload the photos and give them a caption, storing the caption and filename in a text file. It's a bit buggy when removing the photos and captions from the file, and also in displaying them on the delete page. you can see it in action at www.4am.com.au/gallery/upload.php...

Hello. The last weeks I've been coding a roguelike (you know, like nethack) in python using the nCurses library.
