Getting all names in an enum as a String[]

Question

What\'s the easiest and/or shortest way possible to get the names of enum elements as an array of Strings?

What I mean by this is that if, for example,

Answer 1

Another ways :

First one

Arrays.asList(FieldType.values())
            .stream()
            .map(f -> f.toString())
            .toArray(String[]::new);

Other way

Stream.of(FieldType.values()).map(f -> f.toString()).toArray(String[]::new);

Answer 2

Try this:

public static String[] vratAtributy() {
    String[] atributy = new String[values().length];
    for(int index = 0; index < atributy.length; index++) {
        atributy[index] = values()[index].toString();
    }
    return atributy;
}

Answer 3

My solution, with manipulation of strings (not the fastest, but is compact):

public enum State {
    NEW,
    RUNNABLE,
    BLOCKED,
    WAITING,
    TIMED_WAITING,
    TERMINATED;

    public static String[] names() {
        String valuesStr = Arrays.toString(State.values());
        return valuesStr.substring(1, valuesStr.length()-1).replace(" ", "").split(",");
    }
}

Answer 4

org.apache.commons.lang3.EnumUtils.getEnumMap(State.class).keySet()

Answer 5

the ordinary way (pun intended):

String[] myStringArray=new String[EMyEnum.values().length];
for(EMyEnum e:EMyEnum.values())myStringArray[e.ordinal()]=e.toString();

Answer 6

Very similar to the accepted answer, but since I learnt about EnumSet, I can't help but use it everywhere. So for a tiny bit more succinct (Java8) answer:

public static String[] getNames(Class<? extends Enum<?>> e) {
  return EnumSet.allOf(e).stream().map(Enum::name).toArray(String[]::new);
}
