Help needed regarding Java classes

Hi,
I am facing problem with java classes.I have created an object p of Parameter type and declared it to be static.I have to call a non-static method on it p.add(getTickCount()).This method is imported from package uchicago.src.sim.engine .This is method from interface SimModel of this package .You can refer to this link to know more about the method I am talking about
http://repast.sourceforge.net/api/index.html
When I am compiling the program,it shows an compilation error
"non-static method cannot referenced by static object"
How am I supposed to refer a non-static method using static object.Is there any way I can store the result returned by getTicCount in static variable ?Please help!!!

Thank you
Sadia

Well it will. Why are you declaring your object static?

As you haven't posted any code I wrote a working version of what I thought you might be trying to do:

Code:

public class dyn {
        public dyn() {
                System.out.println(getIt());
        }

        public static int getIt() {
                return 42;
        }
        public static void main(String argv[]) {
                dyn d=new dyn();
        }
}

It is not recommended to call static method using no static object. use class name when you want to call static method. If your design force to do that it simple means there is problem in your design.
