title: How can I specify the regional date format?
body: <p>When I convert a date to a string at java and applies the following pattern:</p>
  
  <pre><code>SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd");
  </code></pre>
  
  <p>output : 2016-07-14</p>
  
  <p>But I want to be as follows.</p>
  
  <pre><code>Japan, Korea user : 2016-07-14
  USA, Canada user : 07-14-2016
  Germany, Australia user : 14-07-2016
  </code></pre>
  
  <p>I can set pattern "if~else", looking for a more general way.
  How can i that?</p>
