Question

This is the question I am stuck on -

In the exercises in Chapter 6, you created a class named Purchase. Each Purchase contains an invoice number, amount of sale, amount of sales tax, and several methods.

Now, write a program that declares an array of five Purchase objects and prompt a user for their values. As each Purchase object is created, continuously prompt until the user enters an invoice number between 1000 and 8000 inclusive and a non-negative sale amount. Prompt the user for values for each object and then display all the values.

This is the code that I am unsure where to fully start -

public class Purchase

{

private int invoiceNumber;

private double saleAmount;

private double tax;

private static final double RATE = 0.05;

public void setInvoiceNumber(int num)

{

invoiceNumber = num;

}

public void setSaleAmount(double amt)

{

saleAmount = amt;

tax = saleAmount * RATE;

}

public double getSaleAmount()

{

return saleAmount;

}

public int getInvoiceNumber()

{

return invoiceNumber;

}

public void display()

{

System.out.println("Invoice #" + invoiceNumber +

" Amount of sale: $" + saleAmount + " Tax: $" + tax);

}

import java.util.*;

public class PurchaseArray {

public static void main(String[] args) {

// Write code here

}
