      • copyFields

        public static <E> void copyFields​(@NonNull
                                  E source,
                                  @NonNull
                                  E target)
        Copy Object source to Object target. This coping is not recursive. If a source field is Collection, it's element will be Collection.addAll(Collection) to corresponding target field, instead of copy the Collection reference. Hence if target's Collection is not initialized and remains null, it won't be copied.

      • copyFieldsExcluding

        public static <E> void copyFieldsExcluding​(@NonNull
                                           E source,

                                           java.lang.String... fields)
        Parameters:
        fields - to be excluded for copying

        This method doesn't always function as expected. Be 100% sure and tested when you use it. As known, this method is not worked for following case: * parameter type is primitive number, e.g. int.class * parameter type is general type, e.g. Object.class
