Question

我正在尝试用Java阅读和处理几种语言的词典。那么如何根据这个安排我的代码呢？感谢。

要将它们变为大写，我使用了这个：

     String str_uc=str.toUpperCase(Locale.ENGLISH);

但它不支持其他语言，我正在尝试阅读。

然而，主要问题是我在将它们变成大写之前无法正确读取其他语言的文件。

这是我到目前为止所做的。适用于英语词典。

Answer 1

我将每个文件编码为UTF-8

对于每个语言，我会将每个字典读成Set<String>可能是NavigableSet<String>，我会将这些字典放在一个由该语言键入的地图上。

Answer 2

另一种方法是在地图中使用单词作为键：

HashMap<(String) word ,Set<(String) codeLanguage>>

并且正如Peter Lawrey所说，在同一张地图中

 <(String) codeLanguage, Set(String) allLanguageWorld>>

如果使用东方语言，则必须使用Unicode。
