您可以先收集到TreeMap，仅获取最后一个条目(最大值为

You could collect to a TreeMap first and only get the last entry (where the max is)

players.stream()
       .collect(Collectors.groupingBy(
           Player::getPoints,
           TreeMap::new,
           Collectors.toList()
       ))
       .lastEntry()
       .getValue();
