Java: How to limit access of a method to a specific class?

Question

Here's an example:

class A 
{
   List l = new List ();
   list.insert("x");
}

class List
{
   ...
   public void insert ()
   {
      /*insertion occurs*/
   }
   ...
}

Is it possible at all to keep the insert() method public, but limit access only to class A so that no other class can access it, only when called from A?

Answer 1

The best you can do using access modifiers is to make the method package private (remove the public keyword) and keep only those two classes in the same package.
