title: Get All Possible Available Currencies
body: <p>I would like to get all possible available currencies.</p>
  
  <p>Java 7 had provided such feature.</p>
  
  <pre><code>public static Set&lt;java.util.Currency&gt; java.util.Currency.getAvailableCurrencies()
  </code></pre>
  
  <p>However, I am still using Java 6 for development and deployment. May I know how I can get all possible available currencies? Code example are most welcomed.</p>
