Use Static Factory Methods

Static factory methods let you implement object pool or return sub-types, which is useful in a service-provider scenario. However, be careful about the open-and-init anti-pattern.

A static factory method should immediately return an object to its caller once the object is constructed to a “close-able” state. After that, the caller may manage the object with a try-with-resources statement and continues initializing the object. Should the object raises any exception during the initialization, it is closed properly.
