[java] Filling a List with all enum values in Java

I would like to fill a list with all possible values of an enum
Since I recently fell in love with EnumSet, I leveraged allOf()

EnumSet<Something> all = EnumSet.allOf( Something.class);
List<Something> list = new ArrayList<>( all.size());
for (Something s : all) {
    list.add( s);
}
return list;

Is there a better way (as in non obfuscated one liner) to achieve the same result?

There is a constructor for ArrayList which is

ArrayList(Collection<? extends E> c) 

Now, EnumSet extends AbstractCollection so you can just do

ArrayList<Something> all = new ArrayList<Something>(enumSet)

try

enum E {
    E1, E2, E3
}

public static void main(String[] args) throws Exception {
    List<E> list = Arrays.asList(E.values());
    System.out.println(list);
}

Try this:

... = new ArrayList<Something>(EnumSet.allOf(Something.class));

as ArrayList has a constructor with Collection<? extends E>. But use this method only if you really want to use EnumSet.

All enums have access to the method values(). It returns an array of all enum values:

... = Arrays.asList(Something.values());

Class.getEnumConstants()

List<SOME_ENUM> enumList = Arrays.asList(SOME_ENUM.class.getEnumConstants());

List<Something> result = new ArrayList<Something>(all);

EnumSet is a Java Collection, as it implements the Set interface:

public interface Set<E> extends Collection<E> 

So anything you can do with a Collection you can do with an EnumSet.

This is a bit more readable:

Object[] allValues = all.getDeclaringClass().getEnumConstants();

You can use also:

Collections.singletonList(Something.values())

private ComboBox gender;
private enum Selgender{Male,Famle};
ObservableList<Object> observableList  =FXCollections.observableArrayList(Selgender.values());
