I'm having a problem with some java code involving an array and I don't understand the error that appears:
CD.java:67: array required, but CDDriver found
System.out.println(myCD[i]);

I am trying to print out the total of all the prices that are in the array

Any help would be great

here is the whole code

class CD
{
String artist;
String title;
double cost;
static double totalPrice;
static int totalCDs;
double total=0;

CD (String a, String t, double c)
{
artist=a;
title=t;
cost=c;
}

public String toString()
{
return artist + "\t " + title + "\t " + cost;
}

public String getArtist()
{
return artist;
}

public String getTitle()
{
return title;
}

public double getCost()
{
return cost;
}

public static double getTotalPrice()
{
return totalPrice;
}

public int getTotalCDs()
{
return totalCDs;
}

public void setTotalPrice(double newTotalPrice)
{
totalPrice = newTotalPrice;
}

public double findTotalPrice(CDDriver myCD)
{
for (int I=0; I<3; I++)
{
System.out.println(myCD[i].getCost());
}
return total;
}

}
-------------------------------------------------

class CDDriver
{
public static void main(String args[])
{
CD myCD [] =new CD[3];


myCD[0] = new CD("Killers\t","Hot Fuss",6.49);
myCD[1] = new CD("Kaiser Chiefs", "Employment",6.49);
myCD[2] = new CD("Leonard Cohen", "The Essential",7.99);

System.out.println("Artist \t\tTitle\t\tCost");
System.out.println("============================== ======");

for(int I=0; I<myCD.length; I++)
{
System.out.println(myCD[i].toString());
}

int maxIndex=0;
double maxCost=myCD[0].getCost();

for(int I=1; I<myCD.length; I++)
{
if (myCD[i].getCost()>maxCost)
{
maxCost=myCD[i].getCost();
maxIndex=i;
}
}

printTotals(myCD, myCD.length);

System.out.println("\nThe most expensive CD is in location "+maxIndex+" and is: \n"+ myCD[maxIndex].toString());

System.out.println("\n" + "Total price of all CDs is " + CD.getTotalPrice());
}

public static void printTotals(CD[] myCD, int number)
{
System.out.println("Total Number of CDs \t Total Price");

System.out.println(number + "\t\t" + myCD.findTotalPrice());
}


}

Where is the CDDriver class?

Edit: Sorry, I must be blind.

Underneath the CD class
They are separate by a line of dashes

In CDDriver:
[CODE=Java]System.out.println("\n" + "Total price of all CDs is " + CD.getTotalPrice());[/CODE]
CD.getTotalPrice() will return "0" unless you've previously done a CD.setTotalPrice().

More importantly:
[CODE=Java]System.out.println(number + "\t\t" + myCD.findTotalPrice());[/CODE]
Does not match this from the CD class:
[CODE=Java]public double findTotalPrice(CDDriver myCD)[/CODE]

Also you can't do this:
[CODE=Java]System.out.println(myCD[i].getCost());[/CODE]
Because myCD is not an array here.


Try this:
[CODE=Java]class CD
{
String artist;
String title;
double cost;
static double totalPrice;
static int totalCDs;
double total=0;

CD (String a, String t, double c)
{
artist=a;
title=t;
cost=c;
}

public String toString()
{
return artist + "\t " + title + "\t " + cost;
}

public String getArtist()
{
return artist;
}

public String getTitle()
{
return title;
}

public double getCost()
{
return cost;
}

public static double getTotalPrice()
{
return totalPrice;
}

public int getTotalCDs()
{
return totalCDs;
}

public static void setTotalPrice(double newTotalPrice)
{
totalPrice = newTotalPrice;
}

public static void setTotalPrice(CD[] myCD)
{
double total = 0;
for (int i=0; i<myCD.length; i++)
{
total += myCD[i].getCost();
}
totalPrice = total;
}

public static double getTotalPrice(CD[] myCD)
{
double total = 0;
for (int i=0; i<myCD.length; i++)
{
total += myCD[i].getCost();
}
return total;
}

public static double findTotalPrice(CD[] myCD)
{
for (int i=0; i<myCD.length; i++)
{
System.out.println(myCD[i].getCost());
}
return getTotalPrice(myCD);
}

}
[/CODE]
And
[CODE=Java]class CDDriver
{
public static void main(String args[])
{
CD myCD [] =new CD[3];


myCD[0] = new CD("Killers\t","Hot Fuss",6.49);
myCD[1] = new CD("Kaiser Chiefs", "Employment",6.49);
myCD[2] = new CD("Leonard Cohen", "The Essential",7.99);

System.out.println("Artist \t\tTitle\t\tCost");
System.out.println("============================== ======");

for(int i=0; i<myCD.length; i++)
{
System.out.println(myCD[i].toString());
}

int maxIndex=0;
double maxCost=myCD[0].getCost();

for(int i=1; i<myCD.length; i++)
{
if (myCD[i].getCost()>maxCost)
{
maxCost=myCD[i].getCost();
maxIndex=i;
}
}

printTotals(myCD, myCD.length);

System.out.println("\nThe most expensive CD is in location "+maxIndex+" and is: \n"+ myCD[maxIndex].toString());

System.out.println("\n" + "Total price of all CDs is " + CD.getTotalPrice());
}

public static void printTotals(CD[] myCD/*, int number <- not needed*/)
{
System.out.println("Total Number of CDs \t Total Price");

System.out.println(myCD.length + "\t\t" + myCD.findTotalPrice(myCD));
}


}[/CODE]


P.S.: And by the way, I like your taste in music. ;-)
