non-static method cannot be referenced from a static context

Okay, ive got a little project im working on, it has 4 classes, 3 of which contain all non-static methods, and one of which contains the static main routine..

on compiling i get this error:

non-static method printHistory() cannot be referenced from a static context

does anyone know how to get around this error? im calling to a non-static method that i need to run in a main routine. if anyone could share some insight on this topic, that would be much appreciated. I can post more details or even code if anyone needs to know more about what im doing in order to help.

Thanks again.
