Implement a java class named RatingScore that represents a numeric rating for so

Question

Implement a java class named RatingScore that represents a numeric rating for something, such as a movie. Its attributes (instance variables) are:

A description of what's being rated
The rating (score) itself
The maximum possible rating
Reviewer comments

The RatingScore class will have methods to:

Create a new RatingScore (given a description, score, maximum score and comments) [constructor]
Create a new RatingScore (from another RatingScore) [copy constructor]
getDescription
getRating
getMaximumRating
getComments
setDescription
setRating
setMaximumRating
setComments
equals [method to check if one RatingScore is the same as another]
toString [method to turn RatingScore into a string for display], for example:

Rating Score [Hidden Figures movie, 4.75, 5.0, Feel-good film with strong, humorous and independent characters.]

Explanation / Answer

RatingScore.java

public class RatingScore {
   //Declaring instance variables
   private String description;
   private double rating;
   private double maximumRating;
   private String comments;
  
   //parameterized constructor
   public RatingScore(String description, double rating, double maximumRating,
           String comments) {
       this.description = description;
       this.rating = rating;
       this.maximumRating = maximumRating;
       this.comments = comments;
   }
  
   //Copy constructor
   public RatingScore(RatingScore rc) {
       this.description = rc.description;
       this.rating = rc.rating;
       this.maximumRating = rc.maximumRating;
       this.comments = rc.comments;
   }
  
   //Getters and setters
   public String getDescription() {
       return description;
   }
   public void setDescription(String description) {
       this.description = description;
   }
   public double getRating() {
       return rating;
   }
   public void setRating(double rating) {
       this.rating = rating;
   }
   public double getMaximumRating() {
       return maximumRating;
   }
   public void setMaximumRating(double maximumRating) {
       this.maximumRating = maximumRating;
   }
   public String getComments() {
       return comments;
   }
   public void setComments(String comments) {
       this.comments = comments;
   }
  
  
  
   //This method will compare Two RatingScore class objects
   public boolean equals(RatingScore rc) {

       if (comments == null) {
           if (rc.comments != null)
               return false;
       } else if (!comments.equals(rc.comments))
           return false;
       if (description == null) {
           if (rc.description != null)
               return false;
       } else if (!description.equals(rc.description))
           return false;
       if (Double.doubleToLongBits(maximumRating) != Double
               .doubleToLongBits(rc.maximumRating))
           return false;
       if (Double.doubleToLongBits(rating) != Double
               .doubleToLongBits(rc.rating))
           return false;
       return true;
   }
  
   //toString method is used to display the contents of an object inside it
   @Override
   public String toString() {
       return "RatingScore [description=" + description + ", rating=" + rating
               + ", maximumRating=" + maximumRating + ", comments=" + comments
               + "]";
   }
        

}

Test.java

public class Test {

  
   public static void main(String[] args) {
      
       //Creating an RatingScore class object by passing inputs as arguments
       RatingScore rc1=new RatingScore("Hidden Figures movie",4.75,5.0,"humorous and independent characters.");
      
       //Displaying the contents of RatingScore class object
       System.out.println(rc1.toString());
      
       //Creating an RatingScore class object by passing RatingScore class object
RatingScore rc2=new RatingScore(rc1);
    System.out.println(" ::Comparing Two RatingScore objects::");
//Comparing the two RatingScore class objects
boolean bool=rc2.equals(rc1);
if(bool)
   System.out.println("The Rating Score object#1 and Rating Score Object#2 are equal");
else
   System.out.println("The Rating Score object#1 and Rating Score Object#2 are not equal");
   }

}

Output:

RatingScore [description=Hidden Figures movie, rating=4.75, maximumRating=5.0, comments=humorous and independent characters.]

::Comparing Two RatingScore objects::
The Rating Score object#1 and Rating Score Object#2 are equal
