Unit 2 Summary
Unit 2: Using Objects
- Introduces object-oriented programming (OOP) and instantiating objects from classes.
- Discusses method calling and passing parameters to methods.
- Explores constructors, both default and parameterized, to initialize objects.
- Differentiates between primitive data types and reference types (objects).
- Covers basic string manipulations and the
String
class. - Discusses encapsulation and why we use getter and setter methods.
Connections to PBL:
- In the front-end, objects might represent UI components or encapsulate form data to send as JSON to an API.
- The back-end can leverage objects to model real-world entities (e.g., a
User
class to store user information, with methods for updating). - APIs often handle complex objects sent in requests, such as a user profile or order, and parse these into backend models.
