Asking which is the better solution is a bit like asking whether a boat or a bicycle is better. The answer depends on whether there is a road or a river . . .
So it depends on the circumstances which is better. There should be a little about that in Bloch's Effective Java and probably other books.

Eager initialisation:Lazy initialisation:You see f is only instantiated when it is used. In the eager example, f was instantiated immediately.
 
I will suppress my every urge. But not this shameless plug:
