Task 1 is no longer passin!

I son't know why, but it tells me that task 1 isn't longer passing, what I'm doing wrong?

  private String normalizeDiscountCode(String discountCode) {
    this.discountCode = discountCode.toUpperCase();

    for (int i=0; i<discountCode.length(); i++) {// i = i + 1

    char letter = discountCode.charAt(i);//A|B|C...

    if(!Character.isLetter(letter) || letter != '$') {
    throw new IllegalArgumentException("Invalid discount code");
    }

    }
    return discountCode;
  }
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;
  }

  private String normalizeDiscountCode(String discountCode) {
    this.discountCode = discountCode.toUpperCase();

    for (int i=0; i<discountCode.length(); i++) {// i = i + 1

    char letter = discountCode.charAt(i);//A|B|C...

    if(!Character.isLetter(letter) || letter != '$') {
    throw new IllegalArgumentException("Invalid discount code");
    }

    }
    return discountCode;
  }

  public String getItemName() {
    return itemName;
  }

  public int getPriceInCents() {
    return priceInCents;
  }

  public String getDiscountCode() {
    return discountCode;
  }

  public void applyDiscountCode(String discountCode) {
    //this.discountCode = discountCode;
    normalizeDiscountCode(discountCode);
  }
}
Example.java 
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");//THIS IS OUR VOID METHOD
    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"
    }

  }
}
