7,308 PointsHi Steve,
I'm using Atom to edit the code and linux terminal to compile/execute the code.

Roope Jourio
7,308 PointsTo clarify what the file structure looks like.
KaraokeMachine/
com/Karaoke.java // meaning that inside com is Karaoke.java and teamtreehouse folder
teamtreehouse/ // Nothing here (other than model folder)
model/Song.java, SongBook.java // Inside model Song.java and SongBook.java

57,712 PointsHere's a snapshot of this, it isn't my snapshot, it is someone else's code I was helping out in the Community pages. The import & package seems the same at first glance ...
Steve Hunter
57,712 PointsFound this - any help?

7,308 PointsI just ran my code on the work spaces, it works. But for some reason this is not working at all on my PC.
I checked out that link earlier, seemed like a bunch of gibberish to me LOL, I'll go through it again.
So nothing wrong with the code, just some random problem with the project structure.
Steve Hunter
57,712 PointsI think the Stack Overflow post is talking about where you are running the compile command from. You can specify a classpath which tells the compiler where to expect to find code to compile and create your executable code.
This is all far easier in something like Netbeans, Eclipse or Intelli-J - these IDEs will fix your imports for you.

7,308 PointsI just opened the project in IntelliJ and I cannot even run it, it's grayed out.
Trying to optimize imports, (CTRL + ALT + O)But it says that "Unused imports not found"
Roope Jourio
7,308 PointsI'm just gonna keep going and keep pushing the code to Github even though it doesn't work on my pc, no solution found.
Steve Hunter
57,712 PointsThe Github repo has all your TH stuff in it, not just this project. I don't think that'll clone easily as it isn't one contained application. I can't just clone the Karaoke part of it.

57,712 PointsHi there,
I pulled your Github repo into Intelli-J. It errored with the package tree.
As above, with the classpath, deleting the com. part of the package and import statements works fine.
This is because Karaoke is within com. so it doesn't need specifying - this is the root of the compiled classpath.
Make sense?
Steve.
Steve Hunter
57,712 PointsP.S. Pull request sent in Github.
Roope Jourio
7,308 PointsYES! I Added the Karaoke.java inside of the com folder instead of KaraokeMachine folder.
This is working now. Updated github as well.
Thank you Steve for the help!

57,712 PointsGood to get it fixed!

57,712 PointsHi,
Can you take a snapshot of your workspace and paste the link in here. I'll see if I can fix the issue that way. I always get confused looking at the structure! I'll fork your code and get it working, hopefully.
Steve.
