Interface ThrowingBiFunction<T,U,R>

Type Parameters:
T - the type of the first argument to the function
U - the type of the second argument to the function
R - the type of the result of the function
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 ThrowingBiFunction<T,U,R>
Variant of BiFunction whose apply(Object, Object) method is allowed to throw a checked Exception.

It can be used in place of a standard BiFunction when the operation may fail with a checked exception.
