what's the purpose of using run following a main class on the java command line?
<p>I am seeing some code are started like</p>

<pre><code>java MainClass run -cp ******
</code></pre>

<p>I have two questions here,</p>

<ol>
<li>why using run </li>
<li>why specify another classpath following run, any reason or benefit?</li>
</ol>
