If the contained SomeType object is not null then we have to initialize a SomeOtherType object using the fields of the SomeType object and return that new object; otherwise we have to return null Optional<SomeType> SomeType SomeOtherType SomeType We found multiple different solutions where we perform this task with two statements, first retrieving the optional object and then second creating the other type object e.g. private SomeOtherType ourMethod() { SomeType someObject = getOptionalSomeTypeFromSomeWhere().orElse(null); return someObject != null ? new SomeOtherType(someObject.getField1(), someObject.getField2(), ...) : null; } Is it possible to cover this with one statement?
