Join strings with a separator and stripping empty ones
<p>I need the code logic for the following:</p>

<p>These are the three String variables,</p>

<pre><code>String s1 = "A"; String s2 = "B"; String s3 = "C";
</code></pre>

<p>I need to have the following outputs based on the given scenarios:</p>

<ul>
<li>Scenario #1 Actual output should be "A / B / C"</li>
<li>Scenario #2 When s1 is empty, output should be "B / C"</li>
<li>Scenario #3 When s2 is empty, output should be "A / C"</li>
<li>Scenario #4 When s3 is empty, output should be "A / B"`</li>
</ul>

<p>Is this possible using ternary operation?</p>
