Question on String Operation
<p>My understanding of java String got  wrong when i see this code.
I am not sure how this is happening.
Can anyone explain why is so?.</p>

<pre><code>public class NewClass {
    public static void main(String[] args) {
        String str=null;

        System.out.println(str+"Added");
    }
}
</code></pre>

<p><strong>output:nullAdded</strong></p>
