Functional Programming

• Programming

Overview

Closures and recursion are at the base of the functional programming paradigm.

Java 8 introduced lambda expressions, which allow behavior parameterization and functional programming.

Behavior Parameterization

Prior to Java 8, behavior parameterization was possible with anonymous classes. In Java 8, functions can be explicitly passed to the API, as parameters, and returned as results.

Also known as side-effect-free function or stateless function.
