One error

I have one error in Karaoke.java that I just can't figure out. Hopefully someone can assist so that I can go forward. Here is the console error:

Karaoke.java:14: error: cannot find symbol                          
    System.out.printf("There are %d songs. %n", songBook.getSongCoun
t());                                                               
                                                        ^           
  symbol:   method getSongCount()                                   
  location: variable songBook of type SongBook                      
1 error 

And this is my code:

There's a typo in your SongBook class. The method is named getSingCount() instead of getSongCount().

Wow I must be dreaming of singing :) Thanks Livia, I was looking in the wrong file the compile error was pointing at Karaoke while the error is in SongBook how come?

From the compiler's point of view, the problem IS in Karaoke, because that's where you're trying to call a method that doesn't exist. The method getSingCount() is fine by itself, it has proper syntax and all. You could correct the Karaoke class instead to call getSingCount() and it'd work. Of course you meant to write getSongCount() so you'd rather correct the SongBook class than the Karaoke class, but the compiler doesn't know that.
