New question....adding decimal places...

Question

Ok my assignment is thus:The Lone Oak High School Marching Band is raising funds by selling fruit. In order to simplify processing of orders, only three types of packages of fruit are being sold. They are
Box of Apples at a cost of $14.00
Box of Peaches at a cost of $16.00
Box of Oranges at a cost of $18.00
There is a 10.00% tax on the total order amount. Write a Java program that reads the number of each type package on an order and computes the cost for the packages of each type ordered. Total the order, calculate the tax on the order, and the total including the tax. Print all items read and all items calculated with appropriate labels.
Example:
Boxes of Apples: 2
Boxes of Peaches: 3
Boxes of Oranges: 4
Total cost of the fruit: 148.00
Tax: 14.80
Total Amount Due: 162.80
Now ive got the program to work exactly as it should but for neatness i want it to have 2 decimal places. When it runs, ill use the above as an example, it cuts off the second decimal. Is there a nice way to add the the second decimal place?

Answer 1

Try this as an example:
import java.util.Scanner;
import java.text.DecimalFormat;
public class ex
    final static double HOTDOG_COST = 10.00;
    final static double TAX = 0.05;
    public static void main(String[] args)
        DecimalFormat money = new DecimalFormat("$0.00");
        Scanner in = new Scanner(System.in);
        System.out.print("How many hotdogs do you want? ");
        double subTotal = in.nextInt() * HOTDOG_COST;
        double taxCost = subTotal * TAX;
        double total = subTotal + taxCost;
        System.out.println("Cost of food: " + money.format(subTotal));
        System.out.println("Tax: " + money.format(taxCost));
        System.out.println("Total: " + money.format(total));
}
