How does the order of evaluation work in the second form there? Will fallbackIfNullMethodCall() be evaluated even if not returned?

  It can be done this way: result = Optional.ofNullable(nullableVariable) .map(NullableType::someMethodCall) .orElseGet(() -> fallbackIfNullMethodCall());

    This was what I intended to write. Sorry, the HN input box isn't my usual IDE :)

    Makes sense, thanks.

    or even: result = Optional.ofNullable(nullableVariable) .map(NullableType::someMethodCall) .orElseGet(this::fallbackIfNullMethodCall);

  My code contains a bug, the code driver733 wrote is what I intended to write (usually I use predefined variables for orElse, conditionally taking the method call threw me of guard).
