How are functional interfaces introduced in Java 8?

Functional interfaces are a new concept introduced in Java 8. An interface with exactly one abstract method becomes a Functional Interface. We don’t need to use @FunctionalInterface annotation to mark an interface as a Functional Interface.

What is the method reference feature in Java 8?

However, if a class wants to customize the default method then you can provide its own implementation by overriding the method. The Method reference feature introduced in Java 8 is a shorthand notation for Lambda Expressions to call a method of Functional Interface.
