For a uni exercise, I am trying to build a navigation system for a mars rover, for which I am using Eclipse.
My problem is that I don't know how to reference an instanced object outside of the main method, when I try to reference one of the objects it says "[Object name] cannot be resolved" and in the line where I instanced the object it says "the value of the local variable [object name] is not used". Can I only refer to static methods outside the main method?

Yes, you’ll have to make a new instance of that class before accessing non static methods

So I'll have to make a new instance of Main and then run the program from there?

For reference: I the problem occurs when I try to refer to an object method from within a different, instanced object
