能够产生每个元素都唯一的列表是相当有用的功能。 排序是按字典顺序(lexicographically)完成的,因此大写和小写字母位于不同的组中。如果想按字母顺序(alphabetically)对其进行排序,可以向TreeSet构造器传入String.CASE_INSENSITIVE_ORDER比较器. Map 将对象映射到其他对象。
map.put(s,1); } } System.out.println(map); List<String> keyList = new ArrayList<>(map.keySet()); Collections.sort(keyList,String.CASE_INSENSITIVE_ORDER); for(String key : keyList){ System.out.println(key + ":" + map.get(key)); ...
