Your Rating class should have the following fields and methods: private double sumofRatings the sum of all of the ratings private int raters the number of people who have rated an item public Rating () initialize both fields to zero public Rating(double sumOfRatings, int raters) to the parameter values initialize the fields increase the sumOfRatings by public void addRating (double newRating) newRating and increase the number of raters by one public double getAverageRating () are no raters so far, return 0.0 return the average rating; if there public String toString () reviews it is based on; display the average rating and how many for example, if the sum of the ratings is 32 and that is based on ratings from ten people, the toString method will return "3.2 based on 10 reviews" Your Rating class should also implement the Comparable interface – Ratings should be sorted such that the highest average rating appears first. If two Rating objects have the same average, the one with the higher number of reviews should appear first. Example If your class is used with this driver code: Rating r1 System.out.println("rl: " rl.addRating (5); System.out.println("r1: rl.addRating (3.5); = new Rating(); + r1); + r1); System out nrintln ("r1: r1). 9:49 PM e Type here to search 26°F Cloudy 1/17/2022 (8)
