How to get all enum values in Java?
Call Class#getEnumConstants to get the enum’s elements (or get null if not an enum class).
Object[] possibleValues = enumValue.getDeclaringClass().getEnumConstants();
YourEnumClass[] yourEnums = YourEnumClass.class.getEnumConstants();
Or
YourEnumClass[] yourEnums = YourEnumClass.values();
