Package in Java
<p>When do we actually use the package keyword? What does it mean?</p>

<p>Suppose I write the following code:</p>

<pre><code>package masnun;    
public class masnun{
    public static void main(String args[]) {
            System.out.println("Hello maSnun!");
        }


}
</code></pre>

<p>What does this package thing do? I get a masnun.class file that doesn't run. I am new to Java. Can somebody please explain?</p>

<p>Thanks</p>
