title: String.format: 2 => 02
body: <pre><code>       String formatted = String.format("%d:%d", 2, 5);
  </code></pre>
  
  <p>I will output <code>2:5</code></p>
  
  <p>But I want: <code>02:05</code>, and I don't want extra zero for numbers > 9. In this case it should show like: <code>10:35</code></p>
  
  <p>How can I modify <code>String.format</code> method to work in this way?</p>
  
  <p>Thank you!</p>
