title: Comparing two strings for "greater than '0' ..and NULL"
body: <p>I am trying to dig my way through the strict Java methods and operators, but now, trying to 'translate' a piece of PHP code to Java (Android), I'm kinda stuck.</p>
  
  <p>In PHP:</p>
  
  <pre><code>if ($row['price']&gt;'0'){
    (.. do something if price is defined - and higher than zero ..)
  }
  </code></pre>
  
  <p>The problem is that $row['price'] may be empty (in Java: null?) or contain '0' (zero).
  But how can I code that in Java in a smart and not too complicated way? </p>
