You can define for example (not tested code)
public enum Currency {
USD ("USD",840,2,"US dollar"),

private String code;
private int num;

private String currency;
You're likely better off making these variables 'final'.
Ah yes, that makes sense.
Currency(String curCode, int curNum, int curDec, String currency) {
this.code = curCode;
this.num = curNum;
this.decimals = curDec;
this.currency = currency;
}
@Override
public String toString() {
return this.code;
}
// etc methods to return the other values
}
Use more meaningful enum names, though, like 'US', 'EUR', etc.
I'd say use the ISO currency codes [1] while you're at it.

Excellent advice.
