andThen( Function<? super R, ? extends V> after)
Returns a composed function that first applies this function to
its input, and then applies the after function to the result.

BiFunction<T, U, V>
andThen
(Function<? super R, ? extends V> after)
Returns a composed function that first applies this function to
its input, and then applies the after function to the result.
If evaluation of either function throws an exception, it is relayed to
the caller of the composed function.
Parameters
| after |
the function to apply after this function is applied |
Returns
- a composed function that first applies this function and then
applies the
after function

apply
(T t, U u)

Parameters
| t |
the first function argument |
| u |
the second function argument |
