Difference between String.valueOf(long a) and concatenating ("" + a)
<p>Which approach is better and why ?</p>

<p>If I write</p>

<pre><code>cmissValue = String.valueOf(callDBDatasource.cMiss());
</code></pre>

<p>or</p>

<pre><code>cmissValue = "" + callDBDatasource.cMiss();
</code></pre>

<p>What should be the approach?</p>
