Additional Notes
Sealed Class vs Abstract Class?
Track: Java
Topic: Language Upgrades
Focus: Sealed Classes
Java: Sealed Classes
Answer
Sealed classes control inheritance; abstract classes define templates.
While both sealed and abstract classes involve inheritance, they serve different purposes. Sealed classes enforce which subclasses are allowed, whereas abstract classes provide a template for subclasses to implement specific methods. In design, sealed classes are used to secure a hierarchy, while abstract classes are used to ensure that subclasses implement certain methods.
