Definition of Inheritance

Inheritance is one of the core principles of Object-Oriented Programming (OOP), which allows one class (child or derived) to inherit the properties and methods of another class (parent or base). It helps eliminate code duplication and enables the creation of class hierarchies where child classes can extend or override the functionality of the base class.
Types of inheritance include:
Single inheritance — the derived class inherits from only one base class.
Multilevel inheritance — the derived class inherits from a class that, in turn, inherits from another class.
Multiple inheritance — a class can inherit properties and methods from multiple classes (available in some languages, e.g., Python).

Context of usage for Inheritance

• “Inheritance allows creating new classes that reuse the properties and methods of existing classes.”
• “Through inheritance, a child class can access and override the methods of the base class as needed.”
• “In Java, the Car class can inherit the Vehicle base class, gaining access to all its properties and methods.”
• “A child class can use all methods and variables of the base class without redefining them.”
• “The SportsCar class can inherit the Car class, which itself inherits the Vehicle class.”
• “In multilevel inheritance, each subsequent class inherits the properties of all preceding classes.”
• “In Python, the Hybrid class can inherit properties from both ElectricVehicle and FuelVehicle classes.”
• “Multiple inheritance can lead to conflicts if two parent classes have methods with the same names.”
• “Inheritance in Java is implemented using the extends keyword, allowing a subclass to inherit from a parent class.”
• “In Python, inheritance is implemented by specifying the parent class in parentheses after the child class name.”
