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
}
}
