It refers to the bundling of data with the methods that operate on that data. When completing an object-oriented design, there are five basic concepts to understand: classes/objects, encapsulation/data hiding, inheritance, polymorphism, and interfaces/methods. It enables a class to acquire or get the properties from another class, It makes easier to add new features or methods to a class, It provides an overriding feature which allows a child class to have a specific implementation of a method defined in the parent class, A class that is inherited by other classes is termed as super class or parent class or base class, whereas a class that extends another class is termed as sub-class or child class, Inheritance can be classified into majorly 5 types : Single Inheritance, Multilevel inheritance, Hierarchical Inheritance, Multiple Inheritance and Hybrid Inheritance. Inheritance is relevant due to the concept of Code Reusability. Which of the following does not fall under the OOP concept? 48. Methods and attributes only available from other methods in the same class make up the private/internal interface. The data and methods are then enclosed in the object when it is created from the class.
