Question

Answer the following question in Java.

Create a class called Movie. Move should contain:

• Two instance variables: title of type String and rating of type int. Remember to encapsulate them.

• Two constructors: One that takes a tile and rating as arguments and a copy constructor.

• Getter and setter methods for both instance variables.

• A method called getCategory that takes no arguments and return something of type char.

Additional information about the Movie class:

• Title: The instance should always store the string in all upper case, if the method is called with a string that contains any lower case characters, the lower case characters should be converted to upper case.

• Rating must be a value between 0 and 10 (inclusive). If the rating provided is outside of that range, the rating should remain unchanged.

• getCategory: A movie is considered A category if its rating is 9 or 10, B category if the rating is 7 or 8, C category if the rating is 5 or 6, D category if the rating is 3 or 4 and F category otherwise.

Movie Class Code:

public class Movie {
        // Two instance variables: title of type String and rating of type int
        private String title;
        private int rating;

        // Constructor that takes a tile and rating as arguments
        public Movie(String title, int rating) {
                this.title = title.toUpperCase();
                if (rating >= 0 && rating <= 10) {
                        this.rating = rating;
                }
        }

        // Constructor copy constructor
        public Movie(Movie movie) {
                this.title = movie.title;
                this.rating = movie.rating;
        }

        // Setter method to set title of movie
        public void setTitle(String title) {
                this.title = title.toUpperCase();// movie in upper case
        }

        // Setter method to set rating of movie
        public void setRating(int rating) {
                // if entered rating between 0 and 10 (inclusive)
                if (rating >= 0 && rating <= 10) {
                        this.rating = rating;
                }
        }

        // Getter method to get title of movie
        public String getTitle() {
                return title;
        }

        // Getter method to get rating of movie
        public int getRating() {
                return rating;
        }

        // Method getCategory that takes no arguments and return something of type char.
        public char getCategory() {
                // movie is considered A category if its rating is 9 or 10
                if (this.rating == 9 || this.rating == 10) {
                        return 'A';
                }
                // B category if the rating is 7 or 8
                else if (this.rating == 7 || this.rating == 8) {
                        return 'B';
                }
                // C category if the rating is 5 or 6
                else if (this.rating == 5 || this.rating == 6) {
                        return 'C';
                }
                // D category if the rating is 3 or 4
                else if (this.rating == 3 || this.rating == 4) {
                        return 'D';
                }
                // F category otherwise.
                else {
                        return 'F';
                }
        }
}
