2,058 PointsNot sure what my problem is with this Code.
I've tried everything that I could think of. Can someone please explain to me my error? After I try and complete task 2, it tells me that task 1 can no longer pass.
public class Order {
private String itemName;
private int priceInCents;
private String discountCode;
public Order(String itemName, int priceInCents) {
this.itemName = itemName;
this.priceInCents = priceInCents;
}
public String getItemName() {
return itemName;
}
public int getPriceInCents() {
return priceInCents;
}
private String normalizeDiscountCode(String discountCode){
if(! discountCode.matches("[a-zA-Z]+")|| ! discountCode.matches("[$]*")){
throw new IllegalArgumentException("Invalid discount code.");
}
this.discountCode = discountCode;
return discountCode.toUpperCase();
}
public String getDiscountCode() {
return discountCode;
}
public void applyDiscountCode(String discountCode) {
this.discountCode = normalizeDiscountCode(discountCode);
}
}
public class Example {
public static void main(String[] args) {
// This is here just for example use cases.
Order order = new Order(
"Yoda PEZ Dispenser",
600);
// These are valid. They are letters and the $ character only
order.applyDiscountCode("abc");
order.getDiscountCode(); // ABC
order.applyDiscountCode("$ale");
order.getDiscountCode(); // $ALE
try {
// This will throw an exception because it contains numbers
order.applyDiscountCode("ABC123");
} catch (IllegalArgumentException iae) {
System.out.println(iae.getMessage()); // Prints "Invalid discount code"
}
try {
// This will throw as well, because it contains a symbol.
order.applyDiscountCode("w@w");
}catch (IllegalArgumentException iae) {
System.out.println(iae.getMessage()); // Prints "Invalid discount code"
}
}
}

this is not needed:
private String normalizeDiscountCode(String discountCode){
// if you add a $ to the first regex expression and replace the || (or) with a && (and) statement it will pass
// you might not even need the second statement
if(! discountCode.matches("[$a-zA-Z]+")|| ! discountCode.matches("[$]*")){
throw new IllegalArgumentException("Invalid discount code.");
}
// this can be removed because you are setting it in the apply method by calling this method and returning it
this.discountCode = discountCode;
return discountCode.toUpperCase();
}
