And which book might that be? I find enumerations to be quite a natural

switch on them for instance which would not be possile using class

but this is inherently type unsafe). wrote:

You have misconstrued this advice. In the first place, Mr. Bloch was talking
about "enum constructs" such as "private static int LOGOFF = 0;", not the enum
keyword, since it was written before the introduction of that keyword. In the
second place, if you read through that chapter you will see that he advocates
doing exactly what the "enum" keyword does for the same reasons that keyword
exists. In other words, his advice since Java 1.5 translates to "Replace enum
constructs with the enum keyword."
