IllegalArgumentException not applied , could you please help me with this
public class Order {
private String itemName;
private int priceInCents;
private String discountCode;
private String normalizeDiscountCode(String discountCode){
for(char l : discountCode.toCharArray()){
if(Character.isLetter(l) || discountCode.indexOf("$") != -1 ){
discountCode = discountCode.toUpperCase();
}
else if (discountCode.indexOf("$") == -1){
throw new IllegalArgumentException("Invalid discount code.");
}
}
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 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"
