Study Notes

WeatherForecast Class

Defines a class named WeatherForecast for managing weather information.
Contains instance variables:
- skies (string) initialized to an empty string.
- high (integer) initialized to 0.
- low (integer) initialized to 0.
Provides methods for setting and getting:
- set_skies(skies): Stores the weather condition.
- set_high(high): Stores the high temperature.
- set_low(low): Stores the low temperature.
- get_skies(): Returns the current weather condition.
- get_high(): Returns the high temperature.
- get_low(): Returns the low temperature.

Counter Class (Basic)

Defines a class named Counter to track a count.
Contains an instance variable:
- counter (integer) initialized to 0.
Provides methods for:
- increment(): Increases the counter by 1.
- get_value(): Returns the current value of the counter.

Counter Class (With Parameterized Constructor)

Defines another version of the Counter class that takes an initial value.
Contains instance variable:
- counter initialized via constructor.
Provides methods for:
- increment(): Increases the counter by 1.
- decrement(): Decreases the counter by 1.
- get_value(): Returns the current value of the counter.

Counter Class (With Limit)

Defines a Counter class that incorporates a limit for counting.
Contains instance variables:
- counter (integer) and limit (integer) initialized via constructor.
Provides methods for:
- increment(): Increases the counter by 1 if it's less than the limit.
- decrement(): Decreases the counter by 1 if it's greater than 0.
- get_value(): Returns the current value of the counter.

Player Class

Defines a class named Player to manage player information in a game.
Contains instance variables:
- name (string) initialized to an empty string.
- score (integer) initialized to 0.
Provides methods for:
- set_name(name): Sets the player's name.
- set_score(score): Sets the player's score.
- get_name(): Returns the player's name.
- get_score(): Returns the player's score.

ContestResult Class

Defines a class named ContestResult to hold competition results.
Contains instance variables:
- winner, second_place, third_place (all strings) initialized to empty strings.
Provides methods for setting results:
- set_winner(name): Sets the winner's name.
- set_second_place(name): Assigns the name for second place.
- set_third_place(name): Assigns the name for third place.
Additional methods for getting results can be inferred.
