title: Correct formatting for long strings
body: <p>This isn't so much a question with a problem with a section of code but how it should be correctly laid out when a single lengthy sting is forced onto a separate line. </p>
  
  <p>For example say I have the below line of text in a small text area. </p>
  
  <pre><code>JOptionPane.showMessageDialog(null, "The start position must be &gt; 0 and the stop 
  position must be &lt; 12, please try again.");
  </code></pre>
  
  <p>I realise the function of the above code is not hindered by the format but is this the correct way to lay it out? A friend mentioned legally it should be done with concatenation, for example. </p>
  
  <pre><code>JOptionPane.showMessageDialog(null, "The start position must be &gt; 0 and the stop"
                                + "position must be &lt; 12, please try again.");
  </code></pre>
  
  <p>I'll be grateful for any advice. </p>
