Codes that require enhancement:
public interface Order {
void calculateTotal(double price, int quantity);
void placeOrder(String customerName, String address);
void generateInvoice(String fileName);
void sendEmailNotification(String email);
}
public class OrderAction implements Order {
@Override
public void calculateTotal(double price, int quantity) {
double total = price * quantity;
System.out.println("Order total: $" + total);
}
@Override
public void placeOrder(String customerName, String address) {
// Simulate placing order in a system
System.out.println("Order placed for " + customerName + " at " + address);
}
@Override
public void generateInvoice(String fileName) {
// Simulate generating invoice file
System.out.println("Invoice generated: " + fileName);
}
@Override
public void sendEmailNotification(String email) {
// Simulate sending email notification
System.out.println("Email notification sent to: " + email);
}
}
public class OrderTest {
public static void main(String[] args) {
Order order = new OrderAction();
order.calculateTotal(10.0, 2);
order.placeOrder("John Doe", "123 Main St");
// These methods might not be needed for all orders
order.generateInvoice("order_123.pdf");
order.sendEmailNotification("johndoe@example.com");
}
}
