Class: A blueprint or template that defines the properties (attributes) and behaviors (methods) of objects. It specifies what data an object will hold and what operations can be performed on it.
Object: An instance of a class; a concrete entity created based on the class blueprint. Each object has its own set of attribute values and can invoke the class methods.
Attributes (Fields): Data members within a class that hold information about an object’s state (e.g., color, size).
Methods: Functions defined within a class that operate on objects, enabling behavior (e.g., drive(), calculateArea()).
Instantiation: The process of creating an object from a class using a constructor, which allocates memory and initializes the object.
Constructor: A special method used to initialize objects when they are created, often with parameters to set initial attribute values.
1. What is a class in object-oriented programming?
2. Who is the notable computer scientist associated with the formalization of encapsulation principles in object-oriented programming?
3. What is the primary role of inheritance in object-oriented programming?
Classes — definition?
Blueprint for creating objects with attributes and methods.
Encapsulation — role?
Protects object integrity by restricting direct access to data.
Inheritance — mechanism?
Allows a class to acquire properties and behaviors from another class.
Class — definition?
Blueprint defining properties and behaviors.
Object — definition?
Instance of a class.
Attributes — role?
Hold object’s data.
