Functional interface Tutorial - Java 8 features
Java 8 introduced the functional interface as one of its key features.
An interface containing only one abstract method is referred to as a functional interface.
This type of interface is specifically designed to support functional programming paradigms in Java.
The single abstract method within a functional interface is often called the functional method, and it serves as the signature for the lambda expressions or method references associated with that interface.
The @FunctionalInterface annotation is used to explicitly declare an interface as a functional interface, though it's not mandatory for an interface to be functional.
The functional interface is also called Single Abstract Method (SAM) Interfaces.
