Public int getOrderDisc()
{
Return orderDisc;

}
Public class CustomerOrder
{
Public static void main(String[] args)
{
Int ordNum = 1234;
Double ordAmount = 580.00;
Double discountPer = .1;
Order order;
Double finalAmount = order.getOrderAmount() -
Order.getOrderAmount() * order.getOrderDisc() ;
System.out.printf("Final order amount = $%,.2f\n",
FinalAmount) ;
