Answer / Kamlesh Yadav
In Java, there are three main approaches to representing inheritance hierarchies: single inheritance, multiple inheritance (using interfaces), and hierarchical inheritance. Single inheritance involves one superclass and one subclass. Multiple inheritance involves a class inheriting from multiple interfaces or multiple classes using C++-style multiclass inheritance. Hierarchical inheritance, also known as inheritance with multiple parents, involves a common superclass shared by multiple subclasses.
