Making first 1.15 entity, I would be eternally grateful for any help with errors

[Yoseph123]

Have multiple errors including:

 

reason: no instance(s) of type variable(s) T exist so that Class<TutorialEntity> conforms to EntityType<T>

 

Class 'TutorialEntityModel' must either be declared abstract or implement abstract method 'setRotationAngles(T, float, float, float, float, float)' in 'EntityModel'

 

'cubeList' has private access in 'net.minecraft.client.renderer.model.ModelRenderer

 

Cannot resolve symbol 'ModelBox'

 

I have a novice understanding of java while improving I'm still quite in my preliminary stages 

-having problems with importing ModelBox 

-don't know how to make the access on cubelist public 

-I thought I implemented IRenderFactory correctly but apparently I did not 

Forgive me on any negligence on my part this is my first post and aforementioned first entity, again I'm grateful for your consideration for help, thank you
