Get default value if the object is null in Java

Question

I am curious to know how I can write a shorter version of the following code in Java.

I have the following Java class (belongs to JAX-RS):

• javax.ws.rs.core.Response

I need back the int value of the responseStatus if that's possible (response is not null) otherwise default int status value needs to be returned.

I do not want to add any library dependency to my project just for this small piece of code.

This is the code that came up in my mind first:

    private static int getDefaultStatusCodeIfNull(final Response response) {
        if (Objects.isNull(response)) {
            return Response.Status.INTERNAL_SERVER_ERROR.getStatusCode();
        }

        return response.getStatus();
    }

The following code is maybe shorter with lambda but it is so long and hard to read:

    int status = Optional.ofNullable(response)
          .orElse(Response.status(Response.Status.INTERNAL_SERVER_ERROR).build()).getStatus();

Is there any shorter one-line way to get this int value?

Do you think the 2nd one is a better solution than the 1st?

Answer 1

Using ternary operator, maybe?

return (response == null) ? Response.Status.INTERNAL_SERVER_ERROR.getStatusCode() : response.getStatus();
