Question:
You created a class named Purchase. Each Purchase contains an invoice number, amount of sale, amount of sales tax, and several methods. Add get methods for the invoice number and sale amount fields so their values can be used in comparisons. Next, write a program that declares an array of five Purchase objects and prompt a user for their values. Then, in a loop that continues until a user inputs a sentinel value, ask the user whether the Purchase objects should be sorted and displayed in invoice number order or sale amount order. Save the file as SortPurchasesArray.java.
