This will make `tags` be a list, although it doesn't declare the type of the elements of the list.

## List fields with type parameter

But Python has a specific way to declare lists with internal types, or "type parameters":

### Import typing's `List`

In Python 3.9 and above you can use the standard `list` to declare these type annotations as we'll see below. 💡

  public void testToArray_withNull() {
    List<@Nullable Double> list = Arrays.asList((double) 0, (double) 1, null);
    assertThrows(NullPointerException.class, () -> Doubles.toArray(list));
  }

  public void testToArray_withConversion() {
    double[] array = {(double) 0, (double) 1, (double) 2};

    List<Byte> bytes = Arrays.asList((byte) 0, (byte) 1, (byte) 2);

    public void add(final WebApiManager webApiManager) {
        final List<WebApiManager> list = new ArrayList<>();
        Collections.addAll(list, webApiManagers);
        list.add(webApiManager);

        });
    }

    public List<?> getSearchLogList(final SearchLogPager pager) {
        final EsPagingResultBean<?> list;
        if (SearchLogPager.LOG_TYPE_USERINFO.equalsIgnoreCase(pager.logType)) {
            list = (EsPagingResultBean<?>) userInfoBhv.selectPage(cb -> {
                cb.paging(pager.getPageSize(), pager.getCurrentPageNumber());
