BTW, you do know that you can give enums parameters?

enum CarModel
{
    BMW("This is a BMW"),
   HONDA("This is a Honda"),
   FORD("This is a Ford");

  String title;

  CarModel(String aTitle)
  {
     title=aTitle;
  }

  public getTitle()
  {
     return title;
  }
}

CarModel.BMW.getTitle();

Thanks a lot. The tip really helps. I didn't understand this when I was
reading some enum materials found online. They are too confusing. You
cleared my mind. BTW, I think the constructor is private, right?

Not in Wojtek's example.

For me, this is the first real case of private constructor.

enum CarModel
{
   BMW("This is a BMW"),
   HONDA("This is a Honda"),
   FORD("This is a Ford");

  private String title;

  private CarModel(String aTitle)
  {
     title=aTitle;
  }

  public getTitle()
  {
     return title;
  }
}

I would add a static 'fromTitle(String title)' method that works similarly to
'valueOf()' but matches enum values to input title strings.
