What does throws statement mean in java?
<p>Also, what does <code>throws NumberFormatException, IOException</code> mean? I keep trying to use <code>BufferedReader</code> by saying </p>

<pre><code>BufferedReader nerd = new BufferedReader(new InputStreamReader(System.in));
</code></pre>

<p>but <code>BufferedReader</code> won't work unless <code>throws NumberFormatException, IOException</code> is put in.</p>
