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:
- Actual Object Created from a Design (Class)
- An instance is a concrete realization of a class, the blueprint or design.
- 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:
- Class: A car design (details about components and assembly).
- 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.
