Vi o post de outra pessoa, e despertou o interesse de tentar aproveitar melhor o exercício. O que acham ?
Main :
public class Main {
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
System.out.println(menu());
while(true){
try{
System.out.println("Choose the payment type : ");
int paymentCode = scanner.nextInt();
PaymentType paymentType = PaymentType.identifyPaymentType(paymentCode);
System.out.println("Enter the purchase value : ");
double purchaseValue = scanner.nextInt();
Payment payment = new Payment(paymentType,purchaseValue);
double taxValue = payment.calculatePaymentTax();
if(paymentType!=PaymentType.PIX){
System.out.println("Purchase fee amount : " + taxValue);
}
System.out.println("Total value : " + (payment.getValue()+taxValue));
break;
}catch (IllegalArgumentException e){
System.out.println(e.getMessage());
scanner.nextLine();
}
}
}
public static String menu(){
return """
