## Query parameter list / multiple values { #query-parameter-list-multiple-values }

When you define a query parameter explicitly with `Query` you can also declare it to receive a list of values, or said in another way, to receive multiple values.

For example, to declare a query parameter `q` that can appear multiple times in the URL, you can write:

            StreamUtil.split(overrides, "\n").of(stream -> stream.filter(StringUtil::isNotBlank).forEach(s -> {
                final String[] values = StringUtils.split(s, "=", 2);
                if (values.length == 2) {
                    map.put(values[0].trim(), values[1].trim());
                }
            }));
            setExtensionMimeTypeMap(map);
            if (logger.isDebugEnabled()) {

    for (Entry<K, V> entry : entries) {
      resetContainer();
      K k = entry.getKey();
      V v = entry.getValue();

      Set<V> values = multimap().get(k);
      Set<V> expectedValues = copyToSet(values);

      assertFalse(multimap().put(k, v));
      assertEquals(expectedValues, values);
      assertGet(k, expectedValues);
    }
  }

  @MapFeature.Require({SUPPORTS_PUT, ALLOWS_NULL_VALUES})

      return;
    }

    Collection<V> values = map.values();
    if (supportsRemove) {
      try {
        values.removeAll(null);
        // Returning successfully is not ideal, but tolerated.
      } catch (NullPointerException tolerated) {
      }
    } else {
      try {
        values.removeAll(null);
        // We have to tolerate a successful return (Sun bug 4802647)
