This document discusses multilevel hierarchies in Java inheritance. It defines inheritance as a mechanism that allows a subclass to extend a superclass, allowing for hierarchical classification. It explains that a multilevel hierarchy involves multiple layers of inheritance, where a subclass can be used as a superclass for another subclass. An example program is referenced to clearly demonstrate a multilevel hierarchy structure.

Inheritance

3. INTRODUCTION
 Inheritance-is a compile-time mechanism in Java
that allows you to extend a class (called the base
class or superclass) with another class (called
the derived class or subclass).

4.  Inheritance-allows creation of hierarchical
classification
 Superclass-class inherited
 Subclass-class does inheriting

5. CREATING MULTILEVEL HIERARCHY
 Many layers of inheritance
 Use a subclass as a superclass of another
 To understand about multilevel hierarchy clearly see
the following program..

7. CONCLUSION
 We have thus discussed about..
Creating Multilevel hierarchy
