推荐答案

假设顺序无关紧要：使用commons-collections。

Assuming order doesn't matter: use commons-collections.

1. 使用 String.split（）将两个句子拆分成数组。


2. 使用commons-collections' CollectionUtils.addAll 将每个数组添加到一个空 Set 。


3. 使用commons-collections的 CollectionUtils.subtract 方法来获取AB。

1. Use String.split() to split both sentences into arrays of words.
2. Use commons-collections' CollectionUtils.addAll to add each array into an empty Set.
3. Use commons-collections' CollectionUtils.subtract method to get A-B.
