Simplest way to iterate through a Multiset in the order of element frequency?
I just added this feature to Guava, see here for the Javadoc. Edit: usage example of Multisets.copyHighestCountFirst() as per the original question: Multiset<DeviceType> histogram = getDeviceStats(); for (DeviceType type : Multisets.copyHighestCountFirst(histogram).elementSet()) { System.out.println(type + “: ” + histogram.count(type)); }
