Question
Consider a class 'Movie' that contains information about a movie. The class has the following attributes: -The movie name -The MPAA rating (for example, G, PG, PG13, R) -The number of people that have rated this movie as a 1 (Terrible) -The number of people that have rated this movie as a 2 (Bad) -The number of people that have rated this movie as a 3 (OK) -The number of people that have rated this movie as a 4 (Good) -The number of people that have rated this movie as a 5 (Great) Implement the class with accessor an mutator functions for the movie name and MPAA rating.vWrite a function addRating that takes an integer as an input parameter. The function should verify that the parameter is a number between 1 and 5, and if so, increment the number of people rating the movie that match the input parameter. For example, if 3 is the input parameter, then the number of people that rated the movie as a 3 should be incremented by 1. Write another function, getAverage, that returns the average value for all of the movie ratings. Finally, add a constructor that allows the programmer to create the object with a specified name and MPAA rating. The number of people rating the movie should be set to 0 in the constructor. Test the class by writting a main function that creates at least two movie objects, adds at least five ratings for each movie, and outputs the movie name, MPAA rating, and average rating for each movie object.Explanation / Answer

Consider a class Movie that contains information about a movie. The class has the following attributes:
The movie name
The MPAA rating (e.g. G, PG, PG-13, R)
The number of people that have rated this movie as a 1 (Terrible)
The number of people that have rated this movie as a 2 (Bad)
The number of people that have rated this movie as a 3 (OK)
The number of people that have rated this movie as a 4 (Good)
The number of people that have rated this movie as a 5 (Great)
Implement the class with accessors and mutators for the movie name and MPAA rating. Write a method addRating that takes an integer as an input parameter. The method should verify that the parameter is a number between 1 and 5, and if so, increment by one the number of people rating the movie that matches the input parameter. For example, if 3 is the input parameter, then the number of people that rated the movie as a 3 should be incremented by one. Write another method, getAverage, that returns the average value for all the movie ratings.
Test the class by writing a main method that creates at least two movie objects, adds at least five ratings for each movie, and output the movie name, MPAA rating, and average rating for each movie object.
class Movie
{
private String movieName, MPAARating;
private int numRate[5];

numRate[2]=0;
numRate[3]=0;
numRate[4]=0;
}
public String getMovieName()
{
return movieName;
}
public void setMovieName ( String str )
{
this.movieName = str;
}
public String getMPAARating()
{

}
public void setMPAARating ( String str )
{
this.MPAARating = str;
}
public void addRating(int num)
{
if(num>0&&num<=5)
{
numRate[i-1]++;
}
else
{
System.out.println("Number Value Out of Range");
}
}
public double getAverage()
{
return (numRate[0]+numRate[1]+numRate[2]+numRate[3]+numRate[4])/5;
}
public static void main ()
{
Movie obj1=new Movie();
Movie obj2=new Movie();
obj1.addRating(1);
obj1.addRating(2);
obj1.addRating(3);
obj1.addRating(4);
obj1.addRating(5);
obj2.addRating(1);
obj2.addRating(2);
obj2.addRating(3);
obj2.addRating(4);
obj2.addRating(5);
obj1.setMovieName("Dark Knight Rises");
obj2.setMovieName("Hangover 2");
obj1.getAverage();
obj2.getAverage();
// Here you can print whatever you want to !!
