10,799 PointsApplying a Discount Code 2-2.
Im pretty stuck here.. I feel like im close, but when i preview the code it says: ./Order.java:7: error: incompatible types: String cannot be converted to char for (char element : discountCode.split("")).
I really find the java debugger to be useless, rarely do i understand what it is actually saying. Help would be much appreciated!
public class Order {
private String itemName;
private int priceInCents;
private String discountCode;
private String normalizeDiscountCode(String discountCode) { // THIS IS WHERE THE CHALLENGE IS!
for (char element : discountCode.split("")) {
if (! Character.isLetter(element)) {
if (element != '$') {
throw new IllegalArgumentException("Invalid discount code.");
}
}
}
return discountCode.toUpperCase();
}
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 discountCode) {
this.discountCode = normalizeDiscountCode(discountCode);
}
}
