True, but Java already has some form of scope resolution (the
over-overloaded '.' operator). While it may be painfully reminiscent
of C++, '::' (or some other unique token, but one may as well follow
precident) to unamigiously name things would have been a better choice
than '.'.
That aside, if you want to have a class which implements two
interfaces, and those interfaces happen to both have methods same
signature (and otherwise unrelated), you just can't do it. You can
implement one, but not both, and I'm not sure if the spec says which
method will be implemented (perhaps both, which would be an awful
mistake). You can rename one interface's method, but that may not be
possible, and is needless ugliness regardless.
