Question

I came across this problem that I without knowing the actual enum type I need to iterate its possible values.

if (value instanceof Enum){
   Enum enumValue = (Enum)value;
}

Any ideas how to extract from enumValue its possible values ?

Answer 1

Call Class#getEnumConstants to get the enum’s elements (or get null if not an enum class).

Object[] possibleValues = enumValue.getDeclaringClass().getEnumConstants();
