1. Switch operats on the layer 2, data link layer (of course, the regular
switch, not the layer-3 or layer-4 switch)
2. Router operates on the IP layer, layer 3
So, to answer you question:
Switches don't know the routing. If they are connected to the same subnet,
nothing needs to be done. If they are connected to the different subnet, you
need to put a router between them. Switch isn't counted as a hop, router is.

third, getmethod(String) only returns method object. If you can somehow to

发帖数: 685 | 30 The example you gave is actually another good interview question:
the static point will be deleted more than once if there are multiple objects whose

assigning it with 0 after deleting is a good technique.
However, this is a different question from mine.
There is no such thing as "recursive deleting" involved in both scenarios. |

发帖数: 4965 | 31 regarding ur #5,
web search seems to say that map::erase() SHOULD call destructor,
so the real point of this question is rather uninteresting,
just the difference between destructing container content and removing
the content, which everyone knows. yes the actual behavior is not
defined , so it's bad to expect the interviewee to see this --- in fact
I always assumed that the destructor is NOT called.
