* A JID consists of three parts:

* </p>
* The easiest way to create a JID is to use the {@link #of(CharSequence)} method:
* ```java

* ```
* You can then get the parts from it via the respective methods:
* ```java
* String local = jid.getLocal(); // juliet
* String domain = jid.getDomain(); // capulet.lit
* String resource = jid.getResource(); // balcony
* ```
* Implementations of this interface should override <code>equals()</code> and <code>hashCode()</code>, so that different instances with the same value are equal:
* ```java
* Jid.of("romeo@capulet.lit/balcony").equals(Jid.of("romeo@capulet.lit/balcony")); // true

* The default implementation of this class also supports <a href="https://xmpp.org/extensions/xep-0106.html">XEP-0106: JID Escaping</a>, i.e.
