public enum Brand {
  // Your code here 
  JVC,
  SONY,
  COBY,

  Brand(String displayName) {
    mDisplayName = displayName;

you need to pass the arguments through to the constructor.

package com.example.model;

public enum Brand {

    JVC("JVC"),
  SONY("Sony"),
  COBY("Coby"),
  APPLE("Apple");

    private String mDisplayName;

  Brand(String displayName) {
    mDisplayName = displayName;
  }

  public String getDisplayName() {
    return mDisplayName;
  }
}

(i'd assume that the presence of a constructor means that the default no arg constructor isn't created. If you added a no arg constructor, then the code would be valid from java's perspective, but not satisfy the task instructions)

Hi

I miss the point in the video when Craig explains how to use a argument with the enum?

E.g APPLE ("Apple");
