使用getResources时未找到FileSystem异常

Question

I am very lost with the concept of getResources

I have put a simple text file in a bin folder which I would like to access as a resource so I can then build and deploy. However when I try to run the jar file I get a file not found error which I think is down to how I am accessing the resource. Can anyone give me some direction as to how to use it.

public class Iterator {
    static ArrayList<String> myFiles = new ArrayList<String>();
    static URL filename= Iterator.class.getResource("/Files/FilesLogged.txt");
    static String folderName;
    static Path p;

    public Iterator() { }

    public static void main(String[] args) throws IOException, SAXException, TikaException, SQLException, ParseException, URISyntaxException, BackingStoreException {       

        Preferences userPrefs = Preferences.userNodeForPackage(TBB_SQLBuilder.class);

        p = Paths.get(filename.toURI());
        //This iterates through each of the files in the specified folder and copies them to a log. 
        //It also checks to see if that file has been read already so that it isn't re-inputted into the database if run again               
        //Loop through the ArrayList with the full path names of each folder in the outer loop
        for (String line : Files.readAllLines(p)){
            myFiles.add(line);
        }   
    }
}

The error I get

Exception in thread "main" java.nio.file.FileSystemNotFoundException
at com.sun.nio.zipfs.ZipFileSystemProvider.getFileSystem(ZipFileSystemProvider.java:171)
at com.sun.nio.zipfs.ZipFileSystemProvider.getPath(ZipFileSystemProvider.java:157)

**Edit with @BorisTheSpiders Answer

public class Iterator {
    static ArrayList<String> myFiles = new ArrayList<String>();

    static URL filename= Iterator.class.getResource("/Files/FilesLogged.txt");
    static String folderName;
    static Path p;
    public Iterator() {
    }

    public static void main(String[] args) throws IOException, SAXException, TikaException, SQLException, ParseException, URISyntaxException, BackingStoreException {       

        Preferences userPrefs = Preferences.userNodeForPackage(TBB_SQLBuilder.class);
        InputStream in = filename.openStream( );
        BufferedReader reader = new BufferedReader( new InputStreamReader( in ) );
             p = Paths.get(filename.toURI());
            //This iterates through each of the files in the specified folder and copies them to a log. 
            //It also checks to see if that file has been read already so that it isn't re-inputted into the database if run again               
            //Loop through the ArrayList with the full path names of each folder in the outer loop
            for (String line : Files.readAllLines(p)){
                myFiles.add(line);
            }               

but Im not really sure how I then use the reader to provide a Paths.get with a uri . I think I'm probably not understanding something fundamental here...

As pointed out in the comments, the file in question cannot be found in the file system.

As a suggestion, try replacing

static URL filename= Iterator.class.getResource("/Files/FilesLogged.txt");

with

static InputStream is = Iterator.class.getResourceAsStream("/Files/FilesLogged.txt");

and the block where the file is read with the following:

try (Scanner scanner = new Scanner(is)) {
   while(scanner.hasNextLine()){
        String line = scanner.nextLine();
        myFiles.add(line);
    }
}
