Instance

What is Instance?

An instance is a concept used in object-oriented programming, referring to the actual “real-world” object created from a design (class).

Key Points:

  1. Actual Object Created from a Design (Class)
    • An instance is a concrete realization of a class, the blueprint or design.
  2. Concept in Object-Oriented Programming
    • In object-oriented programming, an instance represents a specific, created object from a class blueprint.

Detailed Explanation:

  • Class: This is the blueprint or template, defining the attributes (data) and methods (operations) that objects created from this class will have.
  • Instance: This is a specific object created based on the class. For example, if the class is a blueprint for cars, an instance would be an actual car created from that blueprint.

Example:

  1. Class: A car design (details about components and assembly).
  2. Instance: An actual car built from that design (a specific, tangible car).

In Summary:

An “instance” is a specific object created from a class design.
