Interface ThrowingPredicate<T>

Type Parameters:
T - type of the input element
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 ThrowingPredicate<T>
This functional interface allows to not catch an Exception in a lambda expression : use it at your own risk, the exception becomes unchecked. It is recommended to use it only in a method that can throw the Exception type that is unchecked. So the exception can be checked when using the method.
