so which is better approach in Java 17 springboot 3 for checking Null condition

using null

isNewPatient(gosDTO != null ? gosDTO .getIsNewPatient() ? 1 : 0 : null);
referredProviderName(gosDTO != null ? gosDTO .getReferredProviderName() : null);
isMobile(gosDTO != null ? gosDTO .getIsMobile() : null);

or using map with Option.Of

Optional<gosDTO > gosOptional = Optional.ofNullable(gosDTO );

isNewPatient(gosOptional.map(gosDTO ::getIsNewPatient).map(it -> it ? 1 : 0).orElse(null));
referredProviderName(gosOptional.map(gosDTO ::getReferredProviderName).orElse(null));
isMobile(gosOptional.map(gosDTO ::getIsMobile).orElse(null));

or any other better way?
