Interface Predicate<T,E extends Exception>

Type Parameters:
T - the type of the input to the predicate
E - the type of the exception that may be thrown
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,E extends Exception>
Represents a predicate (boolean-valued function) of one argument that might throw an exception.

This is a functional interface whose functional method is test(Object).
