<p>We will implement the Hello World code on the initial transition of the
<span class="emphasis"><em>HelloWorldTop</em></span> actor. Therefore open the state machine editor by right clicking the
<span class="emphasis"><em>HelloWorldTop</em></span> actor in the outline view and select
<span class="emphasis"><em>Edit Behavior</em></span>.
</p>
<p>
</p>
<div class="mediaobject">
<img src="images/015-HelloWorld03.png"></div>
<p>
</p>
<p>The state machine editor will be opened. Drag and drop an
<span class="emphasis"><em>Initial Point</em></span> from the tool box to the diagram into the top level state. Drag and drop a
<span class="emphasis"><em>State</em></span> from the tool box to the diagram. Confirm the dialogue with
<span class="emphasis"><em>ok</em></span>. Select the
<span class="emphasis"><em>Transition</em></span> in the tool box and draw the transition from the
<span class="emphasis"><em>Initial Point</em></span> to the State. Open the transition dialogue by double clicking the transition arrow and fill in the action code.
</p>
<div class="literallayout">
<p>
<code class="code">System.out.println("Hello World !");<br>
</code>
</p>
</div>
<p>The result should look like this:</p>
<p>
</p>
<div class="mediaobject">
<img src="images/015-HelloWorld04.png"></div>
<p>
</p>
<p>Save the diagram and inspect the model file. Note that the textual representation was created after saving the diagram.</p>
