guava之SortedMultiset集合简介

SortedMultiset集合:
   可用于按元素进行排序的集合
   此工具类添加排序功能
   如:
   ForwardingSortedMultiset,
   ForwardingSortedMultiset.StandardDescendingMultiset,
   ImmutableSortedMultiset,
   TreeMultiset

 public static void main(String[] args) {
       /**
	    * java265.com 示例程序
	    */
       String str = "a,b,a,c,d,f,g,r,t,a,s,v,c,x";
       String[] words = str.split(",");
       list<String> list = new ArrayList<String>();
       for (String word : words) {
           list.add(word);
       }
       SortedMultiset<String> sortedMultiset = TreeMultiset.create();

       sortedMultiset.addAll(list);

       for (String s : sortedMultiset) {
           System.out.printf("%s", s);
       }

       for(String key:sortedMultiset.elementSet()){
           System.out.println(key+" count："+sortedMultiset.count(key));
       }

   }
