Effective Java
==============

[Creating and Destroying Objects]

/ Consider static factory methods instead of constructors
+ they have names
+ they are not required to create a new object each time they’re invoked
+ they can return an object of any subtype of their return type
- classes without public or protected constructors cannot be subclassed
