### JavaDoc Requirements

All public classes and methods require JavaDoc with `@param`, `@return`, and `@throws` tags.

### Best Practices

**Null Safety:**
```java

  /** Constructor used to implement {@link #from(String)}, and from subclasses. */
  InternetDomainName(String name) {
    // Normalize:
    // * ASCII characters to lowercase
    // * All dot-like characters to '.'
    // * Strip trailing '.'

    name = Ascii.toLowerCase(DOTS_MATCHER.replaceFrom(name, '.'));

    if (name.endsWith(".")) {
      name = name.substring(0, name.length() - 1);
    }

  fun toMultimap(): Map<String, List<String>> {
    val result = TreeMap<String, MutableList<String>>(String.CASE_INSENSITIVE_ORDER)
    for (i in 0 until size) {
      val name = name(i).lowercase(Locale.US)
      var values: MutableList<String>? = result[name]
      if (values == null) {
        values = ArrayList(2)
        result[name] = values
      }
      values.add(value(i))
    }
