I can't seem to get this to work!

Okay so now let's add a required display name property. At this time, just use the proper case of the brand. eg: SONY should have a display name of Sony.

using the code we just built in IntelliJ, i adapted it for this exercise, but it's not working! am i supposed to use private int display? am i supposed to use different display names? like: SONY("Sony"),

any help would be much appreciated!

package com.example.model;

public enum Brand {
  // Your code here 

private mdisplayName;

 private Brand(mdisplayName) {
        mDisplayName = displayName;
        mDisplayName = displayName.getDisplayName();

 public getdiplayName() {
        return mDisplayName;

Looks like you can use Strings for the displays for this one, i.e. SONY("Sony").

Also, take a closer look at your constructor -- it won't compile as it stands. There are two problem areas: the argument list is malformed and the constructor's final line (which is unnecessary, anyway) is calling an invalid method for the type (which wasn't declared, but was presumably meant to be String).

Finally, check the spelling of your getDisplayName() method!

If you continue to have issues, the following worked for me:

package com.example.model;
public enum Brand {
  JVC("JVC"), SONY("Sony"), COBY("Coby"), APPLE("Apple");
  private String displayName;  
  private Brand(String displayName){
    this.displayName = displayName;
  public String getDisplayName(){
    return this.displayName;

Hope that helps!
