Explanation / Answer

Answer :

Output is as follows,

Final order amount : Rs.522.00

Here I have added my comments for main function.

public static void main(String[] args) {

int ordNum = 4;

double ordAmount = 580.00;

double discountPer = 0.10;

// create object and set data variables to given input

Order orders = new Order(ordNum, ordAmount, discountPer);

double finalAmount;

finalAmount = orders.getOrderAmount() - orders.getOrderAmount() * orders.getOrderDiscount();

// = 580.00 - 580.00 * 0.10

// = 580.00 - 58.00

// = 522.00 <--- answer

// Number format is used to format result into currency format

NumberFormat fmt = NumberFormat.getCurrencyInstance();

System.out.println("Final order amount : " + fmt.format(finalAmount));

}
