Java Question

How can I lookup a Java enum from its String value?

I would like to lookup an enum from its string value (or possibly any other value). I've tried the following code but it doesn't allow static in initialisers. Is there a simple way?

public enum Verbosity {


private static Map<String, Verbosity> stringMap = new HashMap<String, Verbosity>();

private Verbosity() {
stringMap.put(this.toString(), this);

public static Verbosity getVerbosity(String key) {
return stringMap.get(key);


Use the valueOf method which is automatically created for each Enum.

Verbosity.valueOf("BRIEF") == Verbosity.BRIEF

For arbitrary values start with:

public static Verbosity findByAbbr(String abbr){
    for(Verbosity v : values()){
        if( v.abbr().equals(abbr)){
            return v;
    return null;

Only move on later to Map implementation if your profiler tells you to.

I know it's iterating over all the values, but with only 3 enum values it's hardly worth any other effort, in fact unless you have a lot of values I wouldn't bother with a Map it'll be fast enough.
