Sending messages back and forth is at the core of instant messaging. Although individual messages
can be sent and received as packets, it's generally easier to treat the string of messages
as a chat using the <tt>org.jivesoftware.smack.Chat</tt> class.

A chat creates a new thread of messages (using a thread ID) between two users. The
following code snippet demonstrates how to create a new Chat with a user and then send
them a text message:<p>
<div class="code"><pre>
<font color="gray"><i>// Assume we've created an XMPPConnection name "connection".</i></font>
Chat newChat = connection.createChat(<font color="green">"jsmith@jivesoftware.com"</font>, new MessageListener() {
<div class="code"><pre><font color="gray"><i>// Assume we've created an XMPPConnection name
"connection".</i></font>
ChatManager chatmanager = connection.getChatManager();<br>Chat newChat = chatmanager.createChat(<font
color="green">"jsmith@jivesoftware.com"</font>, new MessageListener() {
public void processMessage(Chat chat, Message message) {
System.out.println(<font color="green">"Received message: "</font> + message);
}
});
chat.sendMessage(<font color="green">"Howdy!"</font>);
</pre></div><p>
System.out.println(<font color="green">"Received message: "</font> + message);
}
}); <br>try {
chat.sendMessage(<font color="green">"Howdy!"</font>); <br>} catch (XMPPException e) {<br> System.out.println(&quot;Error Delivering block&quot;);<br>}<br><br>
</pre>
</div>

The <tt>Chat.sendMessage(String)</tt> method is a convenience method that creates a Message
object, sets the body using the String parameter, then sends the message. In the case
that you wish to set additional values on a Message before sending it, use the
<tt>Chat.createMessage()</tt> and <tt>Chat.sendMessage(Message)</tt> methods, as in the
following code snippet:<p>

You'll also notice in the example above that we specified a MessageListener when creating a chat.
The listener is notified any time a new message arrives from the other user in the chat.
The following code snippet uses the listener as a parrot-bot -- it echoes back everything the other user types.<p>
