title: what does static area in java mean?
body: <p>I have encountered the following code:</p>
  
  <pre><code>public final class MainActivity extends ActivityBase
  
  {
  
      static
  
      {
          Logger.create();      
      }
  ...
  
  }
  </code></pre>
  
  <p>what does <code>static</code> area like this means?</p>
  
  <p>What's the advantage using this syntax?</p>
