Question

我有一个包含单词列表的字典文件，我将该文件读入数组列表sArray。然后，我有一本书，我使用字符串解析器来获取本书中的每个字符串，并将其发送到二进制搜索方法bSearch。 bSearch将使用递归二进制搜索来确定是否在包含字典的数组sArray中找到了密钥。如果找不到该单词，则会打印出该单词可能拼写错误。

我的问题是，我得到的词汇输出我知道的事实是在我的词典数组中。我已经确认这些字词已被正确阅读，因此问题归结为使用sArray浏览bSearch。我不确定代码有什么问题。下面列出了一些误报的例子。

这是我字典的粘贴转储的链接;你应该能够在下面搜索这些单词并找到它们。 https://paste.ee/p/wp3qh

示例输出：

乌木可能会被误导 phacelite可能会被误导 holmgang可能会被误导压扁可能会被误解

修改我尝试使用

对数组进行排序

Collections.sort(sArray, String.CASE_INSENSITIVE_ORDER);

结果输出仍为误报

ebracteate可能会被误导

Phaca可能被拼错了

holmberry可能会被误导

sraddha可能会被误导

拼写检查程序是缺少单词
