Thread: Help in icosahedron file please help

can someone help me get this obj file working
This is the code called "Phong.java" that I am trying to run with the icosahedron object file.
I needed to use Phong.java and the teapot input to create a icosahedron
I have code for an isocahedron as well as a file that is supposed to be used as an object loader. I need help figuring out what is wrong with the code.
I am not sure what is wrong but I believe it is the input file because it isn't showing me anything when I run it.
i have attached both my code and object file
please please please
