<body>
There was an internal error.
<h1>An Internal Error Occurred</h1>
<p>During: "Contacting Software Sites"</p>
<p>java.lang.NullPointerException</p>
<p>Explanation:</p>
<p>The error message indicates that a NullPointerException occurred while trying to contact software sites.</p>
<p>A NullPointerException is thrown when code attempts to use an object reference that has a null value.</p>
<h2>Example</h2>
<pre>
<code>
public class SoftwareSite {
public void contactSites() {
String site = null;
System.out.println(site.length());
}
}
public class Main {
public static void main(String[] args) {
SoftwareSite softwareSite = new SoftwareSite();
softwareSite.contactSites();
}
}
</code>
</pre>
<p>In this example, the contactSites() method tries to access the length of a null string, which throws a NullPointerException.</p>
