Weather Program Specification and Pseudo Code

Specification Sheet

Program Name: Weather Program

Description:

This program models weather conditions for different cities by instantiating weather objects, updating their attributes, and calculating weather-related values.

Classes and Methods:

Class: Weather

• Instance Variables:
  • String city – Name of the city.
  • double temperature – Temperature in Fahrenheit.
  • int humidity – Humidity percentage.
  • boolean isStormy – Indicates if it is stormy.
  • char weatherSymbol – Represents the weather condition ('S' for Sunny, 'C' for Cloudy, 'R' for Rainy, etc.).
• Constructors:
  1. Default constructor initializing with default values.
  2. Constructor accepting city and temperature.
  3. Constructor accepting city, temperature, humidity, and isStormy.
  4. Fully parameterized constructor accepting all variables.
• Methods:
  1. updateCity(String newCity) – Updates the city name.
  2. updateTemperature(double newTemperature) – Updates the temperature.
  3. getHumidity() – Returns the humidity.
  4. getWeatherSymbol() – Returns the weather condition symbol.
  5. calculateHeatIndex() – Returns heat index as temperature + (humidity * 0.1).
  6. isExtremeWeather() – Returns true if extreme weather conditions exist.

Class: WeatherMain

Creates Objects:

weather1 = new Weather();
weather2 = new Weather("New York", 75.5);
weather3 = new Weather("Los Angeles", 85.0, 40, false);
weather4 = new Weather("Chicago", 30.0, 85, true, 'R');
    

Calls Methods for Each Object:

• Updates location and temperature.
• Prints humidity and weather condition.
• Calculates and prints heat index.
• Determines if the weather is extreme.

    METHOD Weather(city, temperature)
        SET city = city
        SET temperature = temperature
        SET humidity = 50
        SET isStormy = false
        SET weatherSymbol = 'S'
    END METHOD

    METHOD Weather(city, temperature, humidity, isStormy)
        SET city = city
        SET temperature = temperature
        SET humidity = humidity
        SET isStormy = isStormy

    METHOD updateCity(newCity)
        SET city = newCity
    END METHOD

    METHOD calculateHeatIndex()
        RETURN temperature + (humidity * 0.1)
    END METHOD

    METHOD isExtremeWeather()
        RETURN (temperature > 100 OR temperature < 32 OR humidity > 90 OR isStormy)
    END METHOD

END CLASS

CLASS WeatherMain:
    CREATE weather1 AS Weather()

Files to drop off into google classroom.

You will drop off 4 files into Google Classroom:
	• Your files will be: (Remember the java program is dropped off first.)
		• PX_lastname_Weather.java (Java program that is instantiated)
		• PX_lastname_WeatherTester.java (Java program that instantiates the object)
		• PX_lastname_Weather.png (Screenshot inside Eclipse)
		• PX_lastname_Weather.mp4 (Video running the program)
