Class Definitions Summary
-
Counter Class
- Encapsulates a counter with a variable initialized to zero.
- Contains methods to increment the counter by 1 and retrieve its current value.
- Optionally includes a decrementing functionality and a limit for the counter in advanced versions.
-
Player Class
- Manages player information with attributes for name (string) and score (integer).
- Methods allow setting player name and score, as well as retrieving these values.
-
ContestResult Class
- Tracks results of a contest with attributes for winner, second place, and third place (all strings).
- Provides methods to set and get the values of each placement.
-
WeatherForecast Class
- Handles weather forecasting with attributes for sky conditions (string), high temp (int), and low temp (int).
- Methods set and get these values, allowing updates and retrieval of the latest forecast information.
Key Features of Classes
- Initialization: Instance variables typically initialized in class definitions.
- Methods: Include both mutator (set) and accessor (get) methods for manipulating and retrieving instance variables.
- Encapsulation: Each class bundles data and the corresponding methods, maintaining a clear structure for data management.
Additional Notes
- Constructors are optional, depending on the specific requirements of the class.
- Classes can be extended with functionalities, such as limits on values or additional state management.
