Question

Java program.

Mike's Movie Theater is a local cinema showing the latest Hollywood hits. Create a class called Movie that stores basic information about a single movie: the title, the running time or length of the film (in minutes), the showtimes (as a single string, such as "11:00,3:15,7:30"), and the film's rating (R, PG-13, PG, or G). Include get and set methods for each; the setter for rating should check that the value is one of the four valid options and, if not, should set the rating to "Not Rated". Be sure to include a constructor that allows values to be set upon instantiation. Finally, a method called addPreviews should accept the number of previews to be shown prior to the movie, and then add 2 minutes for each to the movie's running time.

Demonstrate that your class works in a program called MovieDemo. It does not need to have user input, but make sure you demonstrate that all methods and fields work correctly.

Answer 1

import java.util.Arrays;

class Movie {
    private String title;
    private int length;
    private String showTime;
    private String ratings;
    public Movie(String title, int length, String showTime, String ratings) {
        this.title = title;
        this.length = length;
        this.showTime = showTime;
        setRatings(ratings);
    }
    public String getTitle() {
        return title;
    }
    public void setTitle(String title) {
        this.title = title;
    }
    public int getLength() {
        return length;
    }
    public void setLength(int length) {
        this.length = length;
    }
    public String getShowTime() {
        return showTime;
    }
    public void setShowTime(String showTime) {
        this.showTime = showTime;
    }
    public String getRatings() {
        return ratings;
    }
    public void setRatings(String ratings) {
        if(Arrays.asList(new String[] {"R", "PG-13", "PG", "G"}).indexOf(ratings) == -1) {
            this.ratings = "Not Rated";
        } else {
            this.ratings = ratings;
        }
    }

    public void addPreviews(int p) {
        length += 2*p;
    }
    @Override
    public String toString() {
        return "Movie [
title: " + title + "
length: " + length + "
showTime: " + showTime + "
ratings: " + ratings
                + "]
";
    }   

}

public class MovieDemo {

    public static void main(String[] args) {
        Movie SpiderMan = new Movie("Spider Man", 90, "1:00", "PG-13");
        System.out.println(SpiderMan);

        SpiderMan.setRatings("XYZ");
        System.out.println(SpiderMan);

        SpiderMan.addPreviews(4);
        System.out.println(SpiderMan);
    }

}
