Object Oriented counting of classes and summing of totals in created objects

[whitep8]

Hi All,

Im quite new to java and im a little stuck with something so any help you can provide would be greatly appreciated.

I have 2 classes, a CD class and a CDDriver class.

The CD class has the stored variables and a toString accessor. the CD driver creates 3 instances of a CD object, which holds artist, title and cost.

What i wouldnt like to figure out, and ive spent ages doing it, is to count the number of classes (totalCD's) and sum the total of the cost of each CD.

Id also like to output the most expensive CD object value AND list in order of value (Ascending or Decending, doesnt matter).

Any help would be greatly appreciated. Ive looked through the java stuff, but this is my first brick wall.

Regards

Paul

public class CD {
 
     private double totalPrice;
     private int totalCDs;
     private String Artist;
     private String Title;
     private double Cost;
 
 
     public CD(String Artist, String Title, double Cost)
    {
        this.Artist = Artist;
        this.Title = Title;
        this.Cost = Cost;
     }
 
 
    public String toString()
    {
        return "CD details: " + Title +" By: " + Artist + "Price:" + Cost;
 
    }
 
 
}
 

class CDDriver
{
    public static void main(String args[])
    {
 
                CD cd1 = new CD("Kaiser "," up the khazi ",(double) 9.99);
        CD cd2 = new CD("Oasis "," morning glory ",(double) 3.99);
        CD cd3 = new CD("Bob Dylan "," Alreet Sunna ",(double) 6.99);
 
        System.out.println("Artist \t\tTitle\t\tCost");
        System.out.println("====================================");
        System.out.println(cd1.toString());
        System.out.println(cd2.toString());
        System.out.println(cd3.toString());
 
 
    }
}
