title: Switch on Enum does not import class
body: <p>Say I have an Enum as follows:</p>
  
  <pre><code>package stackoverflow.models;
  
  public enum MyEnum {
      VALUE_1,
      VALUE_2;
  }
  </code></pre>
  
  <p>And then I have a POJO which has this Enum as one of its fields:</p>
  
  <pre><code>package stackoverflow.models;
  
  public class MyPojo {
      private MyEnum myEnum;
  
      public MyEnum getMyEnum() {
          return myEnum;
      }
  
      public void setMyEnum(MyEnum myEnum) {
          this.myEnum = myEnum;
      }
  }
  </code></pre>
  
  <p>Now, should I do a <code>switch</code> on <code>MyPojo.getMyEnum()</code>, I do <strong>not</strong> need to import the Enum directly into my class:</p>
  
  <pre><code>package stackoverflow.classes;
  
  import stackoverflow.models.MyPojo;
  
  public class MyClass {
      public static void main(final String... args) {
          final MyPojo pojo = new MyPojo();
          switch(pojo.getMyEnum()) {
          case VALUE_1:
              break;
          case VALUE_2:
              break;
          default:
              break;
          }
      }
  }
  </code></pre>
  
  <p>I was just wondering why this is? How does Java resolve the Enum values if it doesn't import the Enum directly?</p>
