Inheritance is one of the fundamental principles of object-oriented programming (OOP) that enables a new class to acquire the properties and behaviors of an existing class. The existing class is known as the superclass, parent class, or base class, while the new class is called the subclass, child class, or derived class. Through inheritance, the subclass automatically gains access to the accessible fields and methods of the superclass and can also define additional attributes and methods of its own. This mechanism promotes code reusability, extensibility, and hierarchical classification of objects. In Java, inheritance is implemented using the extends keyword for classes and the implements keyword for interfaces. The primary advantage of inheritance is code reusability. Common attributes and methods are written once in the superclass and reused by multiple subclasses, reducing duplication and improving maintainability. It also supports software extensibility, allowing programmers to enhance existing classes without
