title: Hiding certain methods from other packages
body: <p>I have two packages in my project: <code>odp.proj</code> and <code>odp.proj.test</code>. There are certain methods that I want to be visible only to the classes in these two packages. How can I do this?</p>
  <p>If there is no concept of a subpackage in Java, is there any way around this? I have certain methods that I want to be available only to testers and other members of that package. Should I just throw everything into the same package? Use extensive reflection?</p>
