title: Insert variable number of whitespaces in the middle of the string (to format "usage" help)
body: <p>How to refactor this to be one line?</p>
  
  <pre><code>String format = "%-20s";
  System.out.print(String.format(format, "Property name"));
  System.out.println(": property value");
  </code></pre>
  
  <p>Likely I want to have something like this, the question is what <code>format</code> should I use?</p>
  
  <pre><code>System.out.println(String.format(format, "Property name", ": property value"));
  </code></pre>
