Ive test your code,
There's nothing wrong with your code except that the file need for your program doesn't exist... At first execution...
I've test it in a single file,
Asking for Item, category, container and location in JOptionPane mode... -
import java.io.BufferedReader;
-
import java.io.FileReader;
-
import java.io.FileNotFoundException;
-
import java.io.IOException;
-
Is already been linked, since you have - import java.io.*;
-
import java.util.*;
-
import javax.swing.*;
You can erase it...
I am using jdk 1.6.03
And there is no problem... ;-)

1.) StringTokenizer is old. Use the String.split method instead.
2.) Arrays are not the best for object oriented modelling. Create a CD class with title, category e.t.c as fields and store them in an ArrayList<CD>.
3.) Do not use a FileOutputStrea m for writing characters. Use BufferedWriter or PrintWriter instead.
I've test it in a single file,
how do i test it in a single file?
how do i test it in a single file?
The codes above, i mean the code that you have been posted at the top...
Save them in a file, with filename exactly the same with the public class...
Don't forget to follow what r035198x said...

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.

For most users, this new feature is actually very convenient. If you want to control the update process,...
