Side effect method in option <T>?

I am looking for a way to accomplish a task that can do side effects.

I am trying the following:

getOptionalHumanObject()
    .map((Human h1) -> human::getName)
    .do((String name) -> System.out::printLn)
    .do((String name) -> invokeImportentHttpPostRequest(x))
    .map((String name) -> name.length())
    ...

Now the only way I think is to use a filter / map is to do my side effect and return true / the same object.

Are you using additional class methods for side effects before the terminal operation, such as ifPresent?

Why not combine all your operations into one lambda called with ifPresent

?



getOptionalHumanObject()
    .map((Human h1) -> human::getName)
    .ifPresent((String name) -> {
        System.out.printLn(name)
        invokeImportentHttpPostRequest(x)
     });
