I have a working class called Song that consists of two strings, a song title and the name of the artist of the song. I am able to create a "TopTen" object, but whenever I try to use the name of the array "arr" in the TopTen class, I get an error. If anyone could explain why I am getting an error for this simple of a problem, it would be very much appreciated.

```
public class TopTen {

    private Song[] arr;

    public TopTen()
    {
        Song[] arr = new Song[10];
    }

    public int findLength()
    {
        int length = arr.length;
        return length;
    }
}

```
