KaraokeMachine.java- I could use some help!

I'm having quite a bit of trouble figuring out the issue... a typo or maybe a messed up scope? I'd appreciate any insight.

Hi John,

Symbol errors mean that your method is called something else or is invisible at that point in the code. Post your code and I'll have a look!


Sorry - just saw your snapshot! I'm on it ...

You've not got a method called promptSongForArtist? Do you mean promptForArtist?

Sorry I ended up figuring out what was wrong w my code earlier. One of the mistakes was what you pointed out- i had typed promptForArtist instead of promptSongForArtist. I had also corrected line 88 where it says return artist.get(index); i changed to return artists.get(index);.

Thanks for the response tho! I was stumped until i came across someone's screenshot and saw those two mistakes.

Glad you got it sorted. :+1:
