## Default values { #default-values }

You can, of course, use default values other than `None`.

Let's say that you want to declare the `q` query parameter to have a `min_length` of `3`, and to have a default value of `"fixedquery"`:

    // get the first non-null value
    Collection<V> values = map.values();
    for (V value : values) {
      if (value != null) {
        try {
          int unused = value.hashCode();
        } catch (Exception e) { // sneaky checked exception
          return false;
        }
        return true;
      }
