Somewhere in the middle of the horror, he's doing: map.put(((Integer) promoEntryTypes[i].get("id")).toString(), ... So they're integers, but encoded in what we call 'ASCII-coded decimal'. tom -- Per Dementia ad Astra

Queue<Beer> wall = ...; assert wall.size() == 99; while (! wall.isEmpty()) { System.out.println(wall.size() + " bottles of beer on the wall,"); System.out.println(wall.size() + " bottles of beer,"); System.out.println("\tYou take one down,"); Beer beer = wall.remove(); System.out.println("\tPass it around,"); lew.consume(beer); System.out.println(wall.size() + " bottles of beer on the wall.\n"); if (! lew.isSober()) throw new IllegalStateException("Lew is looped"); } assert false; // notreached -- Eric Sosman esosman(a)ieee-dot-org.invalid
