Are class and object the same?
Short answer. No. A class is the design; an object is the real thing.
What does encapsulation wrap?
Data and functions.
Four OOP ideas
| Term | Means |
|---|---|
| Class | blueprint |
| Object | real copy |
| Abstraction | hide details |
| Encapsulation | wrap in class |
Remember
| Class: design |
| Object: real thing |
| Encapsulation: data + functions |
Class or object, same thing? No. A class is a blueprint. An object is its real copy. Abstraction hides details. Encapsulation wraps data and functions together. Class is the design. Object is the real thing. Encapsulation wraps both.
