 * ```java
 * HttpUrl url = HttpUrl.parse("http://who-let-the-dogs.out").newBuilder()
 *     .addPathSegment("_Who?_")
 *     .query("_Who?_")
 *     .fragment("_Who?_")
 *     .build();
 * System.out.println(url);
 * ```
 *
 * This prints:
 *
 * ```
 * http://who-let-the-dogs.out/_Who%3F_?_Who?_#_Who?_
 * ```
