its giving me this error Bummer! Hmmm, I called order.applyDiscountCode("abc") and I expected order.getDiscountCode to equal "ABC", but it was "abc" But I have the toUpperCase in there. Am I suppose to put all this in the applydiscount method?
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) {
this.discountCode = discountCode.toUpperCase();
return this.discountCode;
}
public void applyDiscountCode(String discountCode) {
this.discountCode = normalizeDiscountCode(discountCode);
this.discountCode = 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"
}
}
}

I would say the issue is here
public void applyDiscountCode(String discountCode) { this.discountCode = normalizeDiscountCode(discountCode); this.discountCode = discountCode;
}
you are reassigning this.discountCode to exact value you are passing in (the same argument).
I suspect you mean
public void applyDiscountCode(String discountCode) { this.discountCode = normalizeDiscountCode(discountCode);
}
if this answers your question , please mark the question as answered
