Answer
Sealed classes ensure exhaustive pattern matching.
Sealed classes restrict which classes can extend them, allowing for safe exhaustive checks in switch expressions. This ensures all possible cases are covered at compile time, preventing runtime errors. If a new subclass is added, the compiler will prompt updates to switch statements, enforcing maintainability.
