Calling instance method in Java
<p>Following this tutorial:</p>

<p>In Step 2, this method gets called:</p>

<pre><code>registerForContextMenu(getListView());
</code></pre>

<p>which is a public method of Activity. Now, I'm a bit of a Java newbie here - I thought if you wanted to call an instance method of a superclass you needed to preface it with <strong>this</strong>. E.g. </p>

<pre><code>this.registerForContextMenu(getListView());
</code></pre>

<p>Is it just a style thing here? Is there any difference between </p>

<pre><code>this.registerForContextMenu 
</code></pre>

<p>and simply </p>

<pre><code>registerForContextMenu
</code></pre>
