I just tested. CarModel.class.getName() gives me "A.B.C.CarModel", not
"CarModel". Then I have to extract the string out. Yes, you are right
that your method avoids typos.

I am trying this:

enum CarModel
{
BMW, HONDA, FORD;

static String getEnumName()
//{ return "CarModel";} //weak to typs
{
return ??? //trying to get enum type CarModel and convert to string
"CarModel", to avoid using the String litteral "CarModel". But I cannot
figure out how to do it.
}

}

My mistake, I meant CarModel.class.getSimpleName()
Which is only available since Java 1.5, I had forgotten. Still, a better
idea if available.

Thank you very much. It works well for me.

CarModel.class.getSimpleName() gives me exactly what I want, the String
"CarModel".

CarModel.BMW.getDeclaringClass().getSimpleName();

Though I am also confused. To reach BMW you must already know that it
is a part of CarModel

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?

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;
}
}
