hi,
i imported a package simulation , and in this package there is an iterface. The methods inside this interface are of type public. the only problem i have is when i import this package (like this ==> import Simulation.*
and i want to use the methods of the interface such ==> Simulation.negExp(avrg); it gives an error at the compilation time which is :
non-static method negExp(double) cannot be referenced from a static context.
does it mean that the methods declared in the interface should be static ?
plz help me
thanks in advance
