Couldn't we change the method's signature in this specific case to static?

I was wondering why you didn't make both the method as well as field static in this case. For me it doesn't make sense not to do so, because each and every FactReader object will have the same string array, it's not like the array is going to change with some object. So I'd type:

private static String[] funFacts = {...}

and the method's signature would like something like:

public static String getFact() {...}

This would also allow us to use the method using class reference (FactsBook.getFact()), instead of initializing a FactBook object in the activity, if you know what I mean. However, I'm not completely sure how big of an improvement would that be in comparison to non-static field and method. If someone has has an answer to what the difference is, please share it with community.
