Conveniently map between enum and int / String

by

enum → int

yourEnum.ordinal()

int → enum

EnumType.values()[someInt]

String → enum

EnumType.valueOf(yourString)

enum → String

yourEnum.name()

A side-note:
As you correctly point out, the ordinal() may be “unstable” from version to version. This is the exact reason why I always store constants as strings in my databases. (Actually, when using MySql, I store them as MySql enums!)
