Interface Predicate<K,V>

Type Parameters:
K - key type
V - value type
Functional Interface:
This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
@FunctionalInterfacepublic interface Predicate<K,V>
The Predicate interface represents a predicate (boolean-valued function) of a KeyValue pair. This is a stateless record-by-record operation, i.e, test(Object, Object) is invoked individually for each record of a stream.
