Why can't I call a function from my custom library?

I made a library in java to make calling maps from google maps easier and faster but I can't seem to import the jar file correctly. I followed the answer I found on this page How to create my own java library(API)? but it seems I am still doing something wrong.

I named the package in the library com.googleMaps and then I exported the .jar file and then added that .jar file into my build path of another project. I then made a class, imported com.googleMaps.StaticMap; Which gave me an unused library warning. Finally inside my main method I called DisplayMaps("string"); which is a method inside of StaticMap; But it gives me an error saying the Method does not exist but the unused warning on the import went away.

Error is: The method DisplayMap(String) is undefined for the type MapTest1

Code: 

import com.googleMap.StaticMap;

public class MapTest1
{
    public static void main(String[] args)
    {
        DisplayMap("A Url Goes here"); // This is where im getting the error
    }
}

You should call it with StaticMap.DisplayMap("A Url Goes here");. That's assuming it's a static method.

When calling a static method, you have to specify the class it belongs to, unless you are calling it from another method of the same class.

If it's not a static method, you have to create an instance of StaticMap before calling the method :

StaticMap map = new StaticMap(); 
map.DisplayMap("A Url Goes here");
