title: What does <variable> means?
body: <p>I was looking for some codes to make a Spinner then I noticed that they use an ArrayAdapter like this:</p>
  
  <p><code>ArrayAdapter&lt;CharSequence&gt; adapter =  new ArrayAdapter&lt;CharSequence&gt;(context,android.R.layout.simple_spinner_item );</code></p>
  
  <p>My question is, what does the &lt;> do? I investigate a bit and its not a cast (I think) adn i havent found something yet.</p>
