My final project for my university is to enhance my code in order to have it print out the total price including the discount but before shipping charges and taxes. The rows should be items sold and the columns should be the wait of the items. I am starting to get frustrated, been at this for hours cant seem to figure it out. As a hint he says to use nested loops?

Heres my codes I have 1 main class and 1 test class

package assignment3; public class DataEquations { private int ItemsPurchased; // first number to add private double ItemWeight; // second number to add private double PricePerPound = 3.00; // sum of number1 and number2 private double taxrate = .01; // Tax Rate private double Discount; private double VariablePrice; public DataEquations() { } public DataEquations(int Items, double Weight) { ItemsPurchased = Items; ItemWeight = Weight; } public void setItems(int Items) { ItemsPurchased = Items; } public void setWeight(double Weight) { ItemWeight = Weight; } public int getItems() { return ItemsPurchased; } public double getWeight() { return ItemWeight; } public double getPriceBeforeTaxes() { return ItemsPurchased * ItemWeight * PricePerPound; } public double getPriceAfterTaxes() { return ((getPriceBeforeTaxes() * getDiscount()) + getShipPrice() + getBoxPrice()) * (1 +getTax()); } public double getTotalWeight(){ return ItemsPurchased * ItemWeight; } public double getTax(){ return (taxrate); } public double getDiscount() { if (ItemsPurchased >= 25 & (ItemsPurchased < 50)){ Discount = 1 - .05; } else if (ItemsPurchased >= 50 & (ItemsPurchased < 100)) { Discount = 1 - .10; } else if (ItemsPurchased >= 100 & (ItemsPurchased < 200)) { Discount = 1 - .15; } else if (ItemsPurchased >= 200 & (ItemsPurchased < 500)) { Discount = 1 - .20; } else if (ItemsPurchased >= 500& (ItemsPurchased < 1000)) { Discount = 1 - .25; } else if (ItemsPurchased >= 1000) { Discount = 1 - .30; } else if (ItemsPurchased < 25) Discount = 1; return Discount; } public double getShipPrice(){ if (getTotalWeight() >= 0 & (getTotalWeight() < 10)){ VariablePrice = 2.00; } else if (getTotalWeight() >= 10 & (getTotalWeight() < 50)) { VariablePrice = 4.00; } else if (getTotalWeight() >= 50 & (getTotalWeight() < 100)) { VariablePrice = 8.00; } else if (getTotalWeight() >= 100 & (getTotalWeight() < 500)) { VariablePrice = 12.00; } else if (getTotalWeight() >= 500& (getTotalWeight() < 1000)) { VariablePrice = 20.00; } else if (getTotalWeight() >= 1000) { VariablePrice = 30.00; } return VariablePrice + 2.95; } public double getBoxPrice() { return getTotalWeight() / 10 * 2 ; } public int getBoxes() { int Boxes = (int)(getTotalWeight() / 10 + .9999); return Boxes; } }

and my Main Class
package assignment3; import java.util.Scanner; public class PriceCalculator { public static void main(String[] args) { Scanner input = new Scanner( System.in ); DataEquations price = new DataEquations(); System.out.print( "Enter Number of Items Purchased: " ); // prompt int Items = input.nextInt(); // read first number from user price.setItems(Items); System.out.print( "Enter Weight of Items: " ); // prompt double Weight = input.nextDouble(); // read second number from user price.setWeight(Weight); while ((Items <=0 || (Items >10000000))) System.out.printf("Base Price = $%.2f\n", price.getPriceBeforeTaxes()); System.out.printf("Discount = $%.2f\n", price.getPriceBeforeTaxes() * (1- price.getDiscount())); System.out.printf("Base Price Including Discount = $%.2f\n", price.getPriceBeforeTaxes() * price.getDiscount()); System.out.printf("Ship Price = $%.2f\n", price.getShipPrice()); System.out.printf("Base Price With Discount and Ship Price = $%.2f\n", price.getPriceBeforeTaxes() * price.getDiscount() + price.getShipPrice()); System.out.printf("Number of Boxes Needed = %d\n", price.getBoxes()); System.out.printf("Box Price = $%.2f\n", price.getBoxPrice()); System.out.printf("Subtotal = $%.2f\n", price.getPriceBeforeTaxes() * price.getDiscount() + price.getShipPrice() + price.getBoxPrice()); System.out.printf("Tax on Purchase = $%.2f\n", (price.getPriceBeforeTaxes() * price.getDiscount() + price.getShipPrice() + price.getBoxPrice()) * price.getTax()); System.out.printf("Total Price = $%.2f\n", price.getPriceAfterTaxes()); } }


Thanks for all the help ive been really struggling!


[HENRY: Fixed code tags. And did some formatting]
