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 weatherthis 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.
