Conveniently map between enum and int / String

Question

When working with variables/parameters that can only take a finite number of values, I try to always use Java\'s enum, as in

public enum BonusT         


        

Answer 1

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!)
