871 PointsI'm stuck.
I've been trying this problem for an hour and I can't figure out why I keep getting errors. Can someone please help?
public class Order {
private String itemName;
private int priceInCents;
private String discountCode;
private String normalizeDiscountCode(String discountCode) {
this.discountCode = discountCode.toUpperCase();
return 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;
}
public void applyDiscountCode(String normalizeDiscountCode) {
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"
}
}
}

7,263 PointsI didn't look at the class you're taking so I'm not sure about the expected behavior (for instance, looks like you're expecting some exceptions). But here's some code that needs fixing:
public void applyDiscountCode(String normalizeDiscountCode) {
this.discountCode = normalizeDiscountCode(discountCode);
}
The argument provided for normalizeDiscountCode when you call applyDiscountCode() is being ignored. the parameter should be "discountCode" instead of "normalizeDiscountCode".
