3,801 PointsBummer: java.lang.IllegalArgumentException: Invalid discount code. (Look around Order.java line 21)
What does this mean it says it is working fine in the compiler?? Any help would be much appreciated.
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;
}
private String normalizeDiscountCode(String discountCode){
for(int i = 0; i < discountCode.length(); i++){
char current = discountCode.charAt(i);
if(Character.isLetter(current) || current != '$')
{
throw new IllegalArgumentException("Invalid discount code.");
}
}
return discountCode.toUpperCase();
}
public int getPriceInCents() {
return priceInCents;
}
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"
}
}
}

You are very close. Double check your if
statement conditions on task 2. Your code is saying that if discountCode
is a character to throw the exception. Also, think about the difference between ||
and &&
and how it is processed.
Post back if you're still stuck.
Happy coding,
Ken
