A Weather class is used to represent the weather for a particular day. The Weather class has the day's temperature (int temperature) and whether it is sunny (boolean sunny). The class has a getDescription() method that returns a description of the weather as a String. You will write the getDescription() method.

public class Weather {
    private int temperature;
    private boolean sunny;

    /** Constructs a Weather object with the given temperature and sunny status */
    public Weather(int temp, boolean isSunny) {
        temperature = temp;
        sunny = isSunny;
    }

    /** Returns a weather description based on the temperature and sunny status as described in part a. */
    public String getWeatherDescription() {
        String description = " ";
        //add your if statement and assign description to the appropriate return value.
        return description; 
    }
}

Part a. Write the method getWeatherDescription that returns a String describing the weather based on the temperature and sunny status, as follows:

  • if it is sunny and the temperature is greater than 80 degrees, return Hot and sunny.
  • if it is sunny and the temperature is between 60 and 80 degrees inclusively, return Pleasant and sunny.
  • if it is sunny and the temperature is less than 60 degrees, return Cool and sunny.
  • if it is not sunny and the temperature is greater than 80 degrees, return Hot but cloudy.
  • if it is not sunny and the temperature is between 60 and 80 degrees inclusively, return Pleasant but cloudy.
  • if it is not sunny and the temperature is less than 60 degrees, return Cool and cloudy.

Write Your Response

  • Write code to complete the getWeatherDescription() method in the Java Playground below.
  • Run the code and verify the statements print true for all cases.
    • If any output is false, adjust your code and try again.
