Java Java Objects Delivering the MVP Applying a Discount Code

Please help with my code.

Applying discount code, I don't really understand what is wrong with my code.

Order.java
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;
  }

  public void applyDiscountCode(String discountCode) {
    this.discountCode = discountCode;
  }

  public String normalizeDiscountCode(){
    String discountCode = applyDiscountCode(String discountCode).toUpperCase();
    this.discountCode = discountCode;
    return discountCode;
  }
}

You need to edit the normalizeDiscountCode method to accept a string (the code to be normalized).

You should call the normalizeDiscountCode from within the applyDiscountCode 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;
  }

  public void applyDiscountCode(String discountCode) {
    // send discount code to normalizeDiscountCode and assign the result to this.discountCode
    this.discountCode = normalizeDiscountCode(discountCode);
  }

  private String normalizeDiscountCode(String discountCode){
    // receive a discount code and pass back the UPPERCASE version
    return discountCode.toUpperCase();
  }
}
