Java Inheritance
Java Inheritance is a fundamental object-oriented programming (OOP) concept that allows a class (called a subclass or child class) to inherit fields and methods from another class (called a superclass or parent class). It promotes code reusability and establishes a hierarchical relationship between classes, enabling the subclass to extend or override the functionality of the superclass. This mechanism is implemented using the 'extends' keyword in Java.
Developers should learn Java Inheritance to build modular, maintainable, and scalable applications by reducing code duplication and leveraging polymorphism. It is essential for modeling real-world relationships (e.g., a 'Car' class inheriting from a 'Vehicle' class) and is widely used in frameworks like Spring and Hibernate for creating base classes and configurations. Inheritance is a core skill for Java certification exams and enterprise software development.
