Like this:
default <T extends Enum<T>> T getEnum(String key, Class<T> enumType) {
return Enum.valueOf(enumType, getString(key));
}
default <T extends Enum<T>> T getEnum(String key, Class<T> enumType, T
defaultEnum) {
final String strValue = getString(key);
return strValue == null ? defaultEnum : Enum.valueOf(enumType,
strValue);
}
