Abstract

A functional interface is an interface with a single abstract method, called its functional method. Functional interfaces are ideal for defining a single problem or operation. In Java 8, the API was enhanced to utilize functional interfaces. Many of the functional interfaces can contain static and default methods, making them extendable by the user.
