Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

@FunctionalInterface
public interface Predicate<T>
extends java.util.function.Predicate<T>, java.io.Serializable

A Predicate is a lambda or closure with a boolean result. The method accept should be implemented to indicate the object passed to the method meets the criteria of this Predicate. A Predicate is also known as a Discriminator or Filter.
