Question 17

Define a class named movieMagic with the following description:

Instance Variables/Data Members:
int year - to store the year of release of a movie
String title - to store the title of the movie.
float rating - to store the popularity rating of the movie.
(minimum rating = 0.0 and maximum rating = 5.0)

Member Methods:
i. movieMagic() - Default constructor to initialise numeric data members to 0 and String data member to "".
ii. void accept() - To input and store year, title and rating.
iii. void display() - To display the title of a movie and a message based on the rating as per the table given below.

RatingMessage to be displayed
0.0 to 2.0Flop
2.1 to 3.4Semi-hit
3.5 to 4.5Hit
4.6 to 5.0Super hit

Write a main method to create an object of the class and call the above member methods.

import java.util.Scanner;

public class movieMagic
{
    private int year;
    private String title;
    private float rating;
    
    public movieMagic() {
        year = 0;
        title = "";
        rating = 0.0f;
    }
    
    public void accept() {
        Scanner in = new Scanner(System.in);
        System.out.print("Enter Title of Movie: ");
        title = in.nextLine();
        System.out.print("Enter Year of Movie: ");
        year = in.nextInt();
        System.out.print("Enter Rating of Movie: ");
        rating = in.nextFloat();
    }
    
    public void display() {
        String message = "Invalid Rating";
        if (rating <= 2.0f)
            message = "Flop";
        else if (rating <= 3.4f)
            message = "Semi-Hit";
        else if (rating <= 4.4f)
            message = "Hit";
        else if (rating <= 5.0f)
            message = "Super-Hit";
            
        System.out.println(title);
        System.out.println(message);
    }
    
    public static void main(String args[]) {
        movieMagic obj = new movieMagic();
        obj.accept();
        obj.display();
    }
}
Output
BlueJ output of movieMagic.java
