### Question:
ParamSpace implements Serializable { @Override public String toString() { return String.valueOf(dimensionMap); }  Map<String, List<ParameterDimension<?>>> getDimensionMap(); @Override String toString(); ParamSpace add(String name, ParameterDimension<?> dimension); ParamSpace add(String name, List<A> values); ParamSpace add(String name, List<A> values, List<ParamSpace> subSpaces); ParamSpace add(String name, List<A> values, ParamSpace subSpace); ParamSpace add(String name, Distribution<A> values); ParamSpace add(String name, Distribution<A> values, List<ParamSpace> subSpaces); ParamSpace add(String name, Distribution<A> values, ParamSpace subSpace); List<ParameterDimension<?>> get(String name);  }### Answer:
