Java 从列表中删除几乎相同的字符串（名词复数形式）

我试图识别并删除列表中名词的复数形式。基本上，我希望通过以下测试：

@Test
public void testRemoveNounPlurals(){
    List<String> listWithDups = List.of("friend", "friends", "dog", "dogs", "serious");

    List<String> filteredList = removeDuplicates(listWithDups); // testing this method

    org.assertj.core.api.Assertions.assertThat(filteredList)
            .hasSize(3)
            .containsOnly("friend", "dog", "serious");
}

不完全执行：

public static List<String> removeDuplicates(List<String> list) {

    List<String> maybePlurals = list.stream()
            .filter(s -> s.endsWith("s"))
            .collect(toList()); // friends, dogs, serious

    return list.stream()
             // correctly removes friends and dogs, should keep 'serious'
            .filter( word -> maybePlurals.contains(word.concat("s"))) 
            .collect(toList());
}

此解决方案向每个单词添加一个s，并检查它是否存在，如果存在，则将其删除

public static List<String> removeDuplicates(List<String> list) {
    List<String> result = new ArrayList<>();
    result.addAll(list);

    for (String word : list) {
        String words = word + "s";
        result.remove(words);
    }
    return result;
}

首先进入for循环

谢谢。我就是无法摆脱这么简单的任务。对于任何感兴趣的人，都可以使用list.stream.filterword->编写For循环！word.endsWiths.mapword->word+s.forEachresult:：remove；

if (word.endsWith("s")) {
     continue;
}
