NEED HELP! converting change into dollars, quarters, dimes etc..

Hi guys!

Well my problem is i don't know how to convert the amountGiven to change denominations such as dollars, quarters, dimes, nickels, pennies.. Ive just about given up :mad:

heres my code:

import java.text.NumberFormat;


public class Cashier {

private static final double QUARTER_VALUE = 0.25;
private static final double DIME_VALUE = 0.1;
private static final double NICKEL_VALUE = 0.05;
private static final double PENNY_VALUE = 0.01;
private static final double DOLLAR_VALUE = 1.00;

private static String name;
private static double total;
private double cost;
private int numOfItems;
private double aver;
private double aver1;
private double aver2;
private double change;
private double amountGiven;
String s;

private double penny,nickel,dime,quarter,dollar;

NumberFormat nf = NumberFormat.getCurrencyInstance();

public Cashier()
{
name = "";
s = "";
total = 0.0;
cost = 0.0;
numOfItems = 0;
}

public void add(String name, double cost)
{
this.name = name;
this.cost = cost;
s = s + name + "....." + cost + "\n";
numOfItems = numOfItems + 1;
total = total + cost;
}

public void average()
{
aver = total / numOfItems;
}

public void tendered(double Amount)
{
amountGiven = Amount;
}

public double getAG()
{
return amountGiven;
}

public void makeChange()
{
change = amountGiven - total;
}

public String getName()
{
return s;
}

public double getCost()
{
return cost;
}

public int getNumOfItems()
{
return numOfItems;
}

public double getTotal()
{
return total;
}

public double getAver()
{
return aver;
}

public double getChange()
{
return change;
}

public double Quarter()
{
quarter =(int) change / 25;
change = change % 25;


return quarter;

}

public double Dime(){

dime = (change / 25)/10;


return dime;


}
public double Dollar(){

dollar = (int)amountGiven / 100;
amountGiven = amountGiven * 100;

return dollar;

}

public double nickel(){

nickel = (change / 10)/5;


return nickel;

}
public double Penny(){

penny = (change / 5)/1;


return penny;

}
}

        /*That's all the data your program needs to collect, now let's calculate...
