Only the constants you define are the values of the enum.

diesieben07: So, by constants, you mean the “Bill” in BILL("Bill")?

[jasonlow]

If so, given my previous code, I should be doing something like:
foo.valueOf("Bill")?

[jasonlow]

this gives me an exception as well

[diesieben07]

No, i mean the BILL and TOP_UP. "Bill" is just a value of the transactionType field in the enum constant object. The name of your enum constants (used with valueOf) is "BILL" and "TOP_UP" in your case.

[diesieben07]

If you want to look up an enum object by the transactionType field you would use foo.values().firstOrNull { it.transactionType == "bill" }

[jasonlow]

That is perfect, thank you @diesieben07 !

Or is you know the name of the enum value, there's also a "valueOf" method, so in your case foo.valueOf("BILL") would have worked too.
