what does it mean if i have a compiler error saying "non-static method cannot be referenced from a static context"? I was trying to call a method from another class into a method in the current class I am using, i labeled neither one as static, they are both void methods.

The static data/methods refer to the class, and instance data may be different for different objects from this class. So static methods don't know which object they are calling, if there are several objects, so the compiler doesn't allow a static method to call anything which is not static.
You are not allowed to use the keywords this and super in a static method, either.

I don't know whether this helps your present problem; please post more details.

Hi nida,

Can you please put the code (if small enough that you can put) ? It may help to explain more in details.
