How do I check if an array element exists?
<p>I'm looking for Java's equivalent of PHP's <a href="http://php.net/manual/en/function.isset.php" rel="nofollow">isset()</a>;</p>

<pre><code>int board[][]=new int[8][8];
...
if(isset(board[y][x]))
  // Do something with board[y][x]
</code></pre>

<p>Does such a function exist in Java?</p>

<p>Edit: Sorry, what I meant is that I want to check if <code>board[100][100]</code> exists or not. <code>if(board[100][100])</code> would result in an array out of bounds error.</p>
