Checking if a class is java.lang.Enum

The correct syntax would be:

Enum.class.isAssignableFrom(test.MyEnum.class)

but for enums, here is a more convenient method:

if (someObject.getClass().isEnum()))

Update: for enum items with a body (e. g. that override methods), this won’t actually work.
In that case, use

if (someObject instanceof Enum<?>)

Reference:

• Class.isEnum()
