You could create subclass F to extend A, and then have B and C extend F
instead of A. Then stick the methods in F.
But this could drive you crazy and not work if you have various groupings
of shared methods, since java does not allow multiple inheritance.
Another approach would be to put the methods in A, and begin them with
something like:
if (!((this instanceof B)||(this instanceof C)))
{
throw new exception ("MethodX may only be invoked by classes B and C!!!");
}
