guava之ListMultimap集合简介

ListMultimap集合:
   相对于Multimap容器
     其拥有排序的功能
   如:
   ArrayListMultimap, ForwardingListMultimap,
   ImmutableListMultimap, LinkedListMultimap

 public static void main(String[] args) {
        ListMultimap<String,String> multiMap= ArrayListMultimap.create();
        multiMap.put("k1","java265.com-1");
        multiMap.put("k1","java265.com-2");
        multiMap.put("k2","java265.com-3");
        multiMap.put("k3","java265.com-4");
        for (String s : multiMap.keySet()) {
            Collection<String> lastNames = multiMap.get(s);
            System.out.println(lastNames);
        }
    }
