title: How to add a LineBreak (\n) to a String.format with fixed String as format?
body: <p>In the code below, message is a final String that have a <code>\n</code> inside it, and it doesn't work.</p>
  
  <pre><code>message = format = "Blah %d Blah Blah \nBlah Blah %s Blah"
  interventionSize = number
  UserID = String
  String.format(Dic.message,interventionSize,userID)
  </code></pre>
  
  <p>How can I make the line break in this case, cannot find an answer.</p>
  
  <p>BTW, I cannot use any kind of framework or external jar to do that (old code) have to use Plain Old Java.</p>
