hashMap 获取里面value最大的值得key

public  static  void  main(String[] args) {
    Map<String, Integer> map = new HashMap();
    map.put("1", 8);
    map.put("2", 12);
    map.put("3", 53);
    map.put("4", 33);
    map.put("5", 11);
    map.put("6", 3);
    map.put("7", 3);
    Set<String> set=map.keySet();
    map.entrySet();
    List<Map.Entry<String,Integer>> list = new ArrayList(map.entrySet());
    Collections.sort(list, (o1, o2) -> (o2.getValue() - o1.getValue()));//升序
    System.out.println(list.get(0).getKey());
}
