排序字符串数组 [英] Sorting string array

问题描述

我在Java中有一个字符串数组。我需要根据单词中的字符a的数量（降序）对其进行排序。如果某些单词包含相同数量的字符a，那么我需要按照它们的长度（递减顺序）对这些单词进行排序。如果长度相同，则按字母顺序排列。



示例数组：

I have a string array in Java. I need to sort it by the number of character "a"s within the word (decreasing order). If some words contain same number of character a, then I need to sort those words by their lengths(decreasing order). And if the length is same, then alphabetically.

Example array:

["aaaasd","a","aab","aaaabcd","ef","cssssssd","fdz","kf","zc","lklklklklklk","l"]

需要排序如下：

needs to be sorted like:

["aaaabcd","aaaasd","aab","a","lklklklklklk","cssssssd","fdz","ef","kf","zc","l"]

我尝试过：



我不知道如何制作。你能帮忙吗？
