Advantages of the Static Factory Method

Here are some of the advantages of a Static Factory Method over constructors:

• It provides a better name for the constructor, what it expects, and, sometimes, what it produces.
• We usually don't expect exceptions from a constructor. Exceptions from a regular method, on the other hand, are totally valid.
• Speaking of expectations, we expect the constructor to be fast. 

But those are more psychological advantages. There are also some technological advantages to this approach.
