I have looked over the code and cannot seem to find the error. What am I not noticing?
Thank you in advance!
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 l: discountCode.toCharArray())
{
if (l != '$')
{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"
}
}
}

The task asks you to check if discountCode starts with '$' or if its a string of only letters. by the code you provided, it checks each if each character is not '$' and if it is not, then it throw IllegalArgumentException

1,755 PointsHello Alex, Thank you for identifying my error. It seems like I got lost while reading my own code and did not notice this detail! I went ahead and added the second condition and my code ran without any errors.
Thanks again!
