public List<Person> selectAllPeople() {
return List.of(new Person(UUID.randomUUID(), "From Postgres DB"));
}
What other alternative I can use other than List.of to generate same output?

You could use [`Arrays.asList`](https://docs.oracle.com/javase/8/docs/api/java/util/Arrays.html#asList-T...-) – Mr. Polywhirl Jan 11 '21 at 15:44

You can use Collections.singletonList.
Returns an immutable list containing only the specified object. The returned list is serializable.
return Collections.singletonList(new Person(UUID.randomUUID(), "From Postgres DB"));

You should be careful. There are subtle differences, e.g. https://ideone.com/Vbbgdo – Michael Jan 11 '21 at 15:57

@Michael so immutable != unmodifiable. Looks like you can just wrap the return value with a `unmodifiableList` call. e.g. `return Collections.unmodifiableList(Collections.singletonList(new Person(UUID.randomUUID(), "From Postgres DB")));` – Mr. Polywhirl Jan 11 '21 at 16:10
