1,339 PointsStuck on this normalizeDiscountCode thing
Doesn't want to compile: private String normalizeDiscountCode(String discountCode) { for (char letter : discountCode.toCharArray()) { if (! Character.isLetter(letter) && letter != 's') { throw new IllegalArgumentException("Invalid discount code"); } } return discountCode.toUpperCase(); } it shows the error java.lang something and to check the IllegalArgumentException line. Help, please. Thanks
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;
}
public String getDiscountCode() {
return discountCode;
}
private String normalizeDiscountCode(String discountCode) {
for (char letter : discountCode.toCharArray()) {
if (! Character.isLetter(letter) && letter != 's') {
throw new IllegalArgumentException("Invalid discount code");
}
}
return discountCode.toUpperCase();
}
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"
}
}
}

1,339 PointsOh I just found! I had 's' instead of '$' :))))

1,339 PointsBut I think it was something else originally. After copying the part, restarting the quiz , pasting and changing s to $ it worked
