Hopefully someone can help me. I am trying to load a model I made in Blender into my JOGL program. I was able to manual models working and set up my window but there is something wrong with parsing the .obj wavefront file. No errors in my code that I can see, the ImportedModel class came from a textbook.
Here is the code:

Any help would be appreciated.
Trying to parse a .obj model and use the extracted information to load my model into a JOGL program.
