Why friend directive is missing in Java?

by

Here are a few reasons off the top of my head:

  • friend is not required. It is convenient, but not required
  • friend supports bad design. If one class requires friend access to another, you’re doing it wrong. (see above, convenient, not required).
  • friend breaks encapsulation. Basically, all my privates are belong to me, and that guy over there (my friend).
