I don't understand wrapper class and autoboxing?
<p>I am reading a book called "Java in Two Semesters" and I really don't understand wrapper class and autoboxing.</p>

<p>Can you please explain this to me with some code?</p>

<p>Also this is really bothering me:</p>

<pre><code>Object [] anArray = new Object[20];
anArray[0] = new Integer (37);
</code></pre>

<p>What does <code>Object</code> refer to here, is object a class, and the code is creating an array for it?</p>

<p>I have got the book, I have a slight understanding, I just need someone to explain it to me briefly. If I read something online, I will just get confused.</p>
