I can think of two possible advantages to approach #1:
1) The brevity of the syntax:
#1: MyClass.method();
#2: MyClass.getInstance().method();
2) It is slightly more efficient, since it requires an object
reference.
I tend to use approach #2 if it makes sense to me to think of the
thing as an object, which is usually the case. I will *always* use
this approach if it is in any way logically consistent to have more
than one instance of that object.
