Apparently in Java an URL is equal if the ip is the same, so the following test will succeed (kapaza.be and kapaza.nl have the same ip address).

public void testURLEquals() throws MalformedURLException {
  assertEquals(new URL("http://www.kapaza.be"), new URL("http://www.kapaza.nl"));
}

Just so you know when you get strange results when putting URLs in a Set…  It’s even worse, since this means that comparing URLs needs name resolution, which is a slowdown.  More in the Javadocs.

One solution is to use an URI instead of an URL.  This will fail:

public void testURIEquals() throws URISyntaxException {
  assertEquals(new URI("http://www.kapaza.be"), new URI("http://www.kapaza.nl"));

}

For my 10-day visit to Tokyo, Kyoto, Nara, Hakone and Chiba (my brother-in-law’s wedding), I needed to refactor my internal progamming a bit to avoid OutOfMemoryExceptions.

// This class is package protected to avoid
// external programs messing up.class Brain {

public void handleEvent(MeetNewPersonEvent event) {
...  if (getLocation().equals(Locations.JAPAN)) {
 fireEvent(new BowEvent(event));
}}

public void handleEvent(BowEvent event) {
 // Avoid infinite loop.  The problem is the
// 'esteemed higher' part, the person
// for whom you're bowing may think the same.
 if (event.isPersonEsteemedHigher() && !event.hasBowedTooMuch()) {
 bow();
 } else {
 nod();
 }}

protected void bow() {
 lookSincere();
 smile();
 bendForward();
}

I also needed to reprogram the eating subroutines.

public void handleEvent(FeelingHungryEvent event) {
...  if (getLocation().equals(Locations.JAPAN)) {
 // This was a tricky one to handle,
// the implementation is left
// as an exercise to the reader.
uploadChopsticksRoutine();
}}

The RunForTrainEvent and especially the WaitForTrainEvent could be canceled out since public transportation is much better than the location I originally wrote it for (Belgium).

public void handleEvent(RunForTrainEvent event) {
 if (getLocation().equals(Locations.JAPAN)) {
   stopRunning();
   relax();
   Thread.sleep(5*Timer.MINUTE);
 }
}

Finally, I needed to handle the RunningNoseEvent (extends HasColdEvent) better.

public void handleEvent(RunningNoseEvent event) {
...  if (getLocation().equals(Locations.JAPAN)) {
 // Blowing your nose in public is NOT DONE
// in Japan.  This is considered
// a bit the same as burping.
// Public humiliation is your part when
// this is not checked.
 dipNose();
} else {
 blowNose();
}
}

protected Location getLocation() {
...
if (isCurrentLocationUnknown()) {
 if (bodyTallerThanMostOthers() && friendlyPeople()
       && metroEvery2Minutes()
       && dressCode.equals(Dresscodes.COSTUME)
       && eatingCode.equals(EatingCodes.SHOPSTICKS)) {
  return Locations.JAPAN;
  }
 }
}

} // End class
