I get errors I don't understand when I run my code.

Dalton,

java.lang.ArrayIndexOutOfBoundsException: 1 is caused by your code trying to access an array at index 1 when there are less than 2 elements.

at com.teamtreehouse.model.SongBook.importFrom(SongBook.java:38) at Karaoke.main(Karaoke.java:8) tells us that this happens when the songBook.importFrom method is called from within the main method.

Therefore, we trace the method call and find the array that seems to be having the issue within the importFrom method only to find that your code is perfectly fine:

        public void importFrom(String fileName) {
        try (
                FileInputStream fis = new FileInputStream(fileName);
                BufferedReader reader = new BufferedReader(new InputStreamReader(fis));
        ) {
            String line;
            while ((line = reader.readLine()) != null) {
                String[] args = line.split("\\|");
                addSong(new Song(args[0], args[1], args[2])); //args[1] is out of bounds for some reason
            }
        } catch (IOException ioe) {
            System.out.printf("Problems loading %s %n", fileName);
            ioe.printStackTrace();
        }
    }

Since this code is correct, we need to figure out why the array is not the correct size. Considering the size of the array is dependent on the splitting of items with the | separator, it seems logical that there is an issue reading the songs.txt file into the buffered reader and the line.split assignment to args.

You could do some tests to see if this is indeed the case. Place the following line just above the addSong method:

       System.out.println("The size of args: " + args.length);

You should get something like:

         The size of args: 0
         Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 1
         at com.teamtreehouse.model.SongBook.importFrom(SongBook.java:39)
         at Karaoke.main(Karaoke.java:8)...

The size of the args should be 3 all 15 times if there were no issues.

You might want to get the original songs.txt file and copy over the one you have. Make sure it is in the correct directory location within your project. Complete a clean build of the project.

I hope this helps.

Regards,

Chris

Craig Dennis could you please help

When I was receiving this error I finally realized I had ''' String[] args=line.split("\/");

//should have been the pipe |

String[] args=line.split("\|"); '''
