  <p>Is there any difference between:</p>
  
  <pre><code>String A = "Hello";
  String B = A.concat("Testing");
  </code></pre>
  
  <p>and</p>
  
  <pre><code>String A = "Hello";
  String B = A + "Testing";
  </code></pre>
  
  <p>Yes i know there ain't any difference in the output. Wanted to know if there is any technical difference. Thanks !</p>
