1,961 PointsWhats wrong with my code?
It's telling me after I submit that my question 1 is wrong? I'm only adding to the pre-existing code from question 1 when I submit 2 and it tells me I'm wrong.
public class Order {
private String itemName;
private int priceInCents;
private String discountCode;
public Order(String itemName, int priceInCents) {
this.itemName = itemName;
this.priceInCents = priceInCents;
}
private String normalizeDiscountCode(String discountCode) {
if(!discountCode.matches("[a-z$]")) {
throw new IllegalArgumentException("Invalid discount code.");
}
return discountCode.toUpperCase();
}
public String getItemName() {
return itemName;
}
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"
}
}
}

Treehouse TeacherYes I think so. The first task makes sure that you:
You are no longer doing that, you are blocking the code before it gets there. Imagine discount code being
"Abc"
would it pass yourif

1,961 PointsNot related, but is it possible to go back through the java basics course? I feel like there are holes in my knowledge of certain concepts that I may have missed during the first course. I just want to make sure I'm on a good page, and actually know the material before moving forward anymore with my techdegree.
