Can we presume that "java.util.ImmutableCollections" are consistently arranged?

Yes, we can presume that "java.util.ImmutableCollections" are consistently arranged because they are immutable, meaning their content and order cannot be modified after creation. This ensures that the elements in the collection remain in the same order as they were added, and guarantees a consistent arrangement. However, it's important to note that if the elements themselves are mutable, their state can still be changed, which can affect the order they appear in the collection.
