Traditionally, Java programs have returned null as a way to represent that a value isn’t present. The version 8 of the SDK includes a new class which was made specifically to manage missing values.

I won’t describe the details of the Optional class, but very briefly it’s a container object which may or may not contain a non-null value. Therefore, it is possible to manipulate null values as if they were normal instances without necessarily having to perform a null check at every step.

In this article, I’m going to talk about experiences I gathered while working with Java and describe some anti-patterns I’ve seen about such class.
