Question

reate a class Song with the data members listed below:

• title: string the name of the song. (initialize to empty string)
• artist: string the name of the artist. (initialize to the empty string)
• downloads: int the number of times the song has been downloaded. (initialize to 0)

Include the following member functions:

• default constructor,
• a constructor with parameters for each data member (in the order given above),
• getters and setter methods for each data member named in camel-case.  For example, if a class had a data member named myData, the class would require methods named in camel-case: getMyData and setMyData.
• double grossRevenue(double price): This function should take in a price per download and returns the total revenue for the song (revenue = price * downloads).

You only need to write the class definition and any code that is required for that class (i.e., header and implementation).

NOTE: you must not use the implicit "private" for class data types and methods. Include public or private explicitly.

Answer 1

class Song {
   private String title;
   private String artist;
   private int downloads;
  
   public Song() {
       title = "";
       artist = "";
       downloads = 0;
   }

   public Song(String title, String artist, int downloads) {
       this.title = title;
       this.artist = artist;
       this.downloads = downloads;
   }

   public String getTitle() {
       return title;
   }

   public void setTitle(String title) {
       this.title = title;
   }

   public String getArtist() {
       return artist;
   }

   public void setArtist(String artist) {
       this.artist = artist;
   }

   public int getDownloads() {
       return downloads;
   }

   public void setDownloads(int downloads) {
       this.downloads = downloads;
   }
  
   public double grossRevenue(double price) {
       return price * downloads;
   }
}
