What is "String args[]"? in Java
<p>I'm very beginner for programming.</p>

<p>In Java.</p>

<pre><code>public static void main(String []args)
</code></pre>

<p>What's String args? 
and 
What kind of case do you use args at? 
I am fortunate when I have you teach it with  source codes and  examples.</p>
