title: Capitalise first letter in String
body: <p>I'm having trouble converting the first letter to Capital in a String:</p>
  
  <pre><code>rackingSystem.toLowerCase(); // has capitals in every word, so first convert all to lower case
  StringBuilder rackingSystemSb = new StringBuilder();
  rackingSystemSb.append(rackingSystem);
  rackingSystemSb.setCharAt(0, Character.toUpperCase(rackingSystemSb.charAt(0))); 
  rackingSystem = rackingSystemSb.toString();
  </code></pre>
  
  <p>This doesn't seem to work..</p>
  
  <p>Any suggestions?</p>
