Question 16(Multiple Choice Worth 1 points) Consider the following class designed to store weather statistics at a particular date and time:

public class WeatherSnapshot
{
private int tempInFahrenheit;
private int humidity; // value of 56 means 56% humidity
private int dewPoint; // in degrees Fahrenheit
private String date; // stores the date as a String
private int time; // in military time, such as 1430 = 2:30 pm
private boolean cloudy; // true if 25% or more of the sky is covered

// constructor not shown, but it initializes all instance variables
// postcondition: returns temperature
public int getTemp()
{
return tempInFahrenheit;
}

// postcondition: returns date
public String getDate()
{
return date;
}
// postcondition: returns true if precipitation is likely; false otherwise
public boolean precipitationLikely()
{
// implementation not shown
}

// other methods not shown
}

Suppose that a client class named WeeklyWeather stores WeatherSnapshots throughout a week. This class has the following private instance variables:
private ArrayList weatherEvents;
private String startDate; // first date for the week's weather

This class needs a method that creates a subset of all WeatherSnapshot objects that match a certain date. How could this method be implemented?

Add an accessor method to the WeatherSnapshot class that returns true if the date passed as a parameter matches its date instance variable; false otherwise.

Add a method to the WeeklyWeather class that loops through its ArrayList weatherEvents, and returns an ArrayList of WeatherSnapshot objects whose dates match the date passed as a parameter.

Add a method to the WeeklyWeather class that loops through its ArrayList weatherEvents, and finds the number of WeatherSnapshot objects whose dates match the date passed as a parameter.

Add a method to the WeatherSnapshot class that returns an ArrayList of WeatherSnapshot objects that have been created whose dates match the date passed as a parameter.

Add an additional class named WeeklyWeatherSubset that contains a method that loops through the WeeklyWeather ArrayList, and returns an ArrayList of WeatherSnapshot objects whose dates match the date passed as a parameter.
