Multilevel inheritance is a concept in Java where a derived class extends another derived class. This creates a hierarchy of inheritance with a parent class and multiple levels of subclasses.

Multilevel Inheritance Multilevel inheritance involves a chain of inheritance, where a subclass inherits from a superclass, and then another subclass inherits from that subclass.

Java supports class reuse through inheritance and composition. This two-part tutorial teaches you how to use inheritance in your Java programs.

Compare inheritance and composition, the two fundamental ways to relate Java classes, then practice debugging ClassCastExceptions in Java inheritance.

Sealed classes in Java let developers limit the creation and use of subclasses and preserve the class hierarchy. Here is how sealed classes in Java work.
