Poem

🐰 A rabbit hops through code so clean,
Where isEmpty() replaces what had been,
Two length checks vanish, simple and neat,
The refactor's done—victory, complete! ✨

55-56: LGTM! Good use of idiomatic Java.

The refactoring from length() == 0 to isEmpty() improves readability and follows Java best practices. Since the method is private and callers guarantee non-null inputs (checked at lines 23 and 31), this change is safe and semantically equivalent.
