title: How to validate the Currency String in java
body: <p>Suppose I have a currency String in German format:</p>
  
  <pre><code>String money="1.203.432,25";
  </code></pre>
  
  <p>I want to check if money is a valid currency value. 
  "0,00" is valid, "134.20,24" is invalid, "02,23" is invalid and so on. How can I do it in Java?</p>
