title: What is the default package in which my classes are put if I don't specify it?
body: <p>Let's assume I have a file named <code>Main.java</code> with the following code:</p>
  <pre><code>public class Main {
      public static void main(String[] args) {
          System.out.println(&quot;Hello world&quot;);
      }
  }
  </code></pre>
  <p>Is it put in a specific package, in (maybe?) an unnamed package?</p>
