like below code

                 post(() -> route(
                    pathPrefix("scheduleStatus", () ->
                            path("send", () ->
                                    parameter("type", type ->
                                            entity(Jackson.unmarshaller(Car.class), car -> {
                                                return complete(car.getColor());
                                            })
                                    )

                            )
                    ))

can we have default value for type? like we think default car type is bmw etc? how can we achieve this in java akka http?

Akkording to the documentation you cannot do it with parameter() - you need to use parameterOptional():

    post(() -> route(
        pathPrefix("scheduleStatus", () ->
            path("send", () ->
                parameterOptional("type", type ->
                    entity(Jackson.unmarshaller(Car.class), car -> {
                        return complete(car.getColor());
                    })
                )
            )
        )
    )
