推荐答案

Java Strings支持Unicode，所以中文和日文都没问题。但是，可能需要告诉其他工具（例如文本编辑器）和操作系统shell。

Java Strings support Unicode, so Chinese and Japanese is no problem. Other tools (such as text editors) and your OS shell probably need to be told about it, though.

读取或打印Unicode数据时，必须确保控制台或流也支持Unicode（否则它可能会被问号替换）。

When reading or printing Unicode data, you have to make sure that the console or stream also supports Unicode (otherwise it will likely be replaced with question marks).

Writer unicodeFileWriter = new OutputStreamWriter(
    new FileOutputStream("a.txt"), "UTF-8");
unicodeFileWriter.write("漢字");

您可以直接在Java源代码文件中嵌入Unicode文字，但是您需要告诉编译器文件是UTF-8（ javac -encoding UTF-8 ）

You can embed Unicode literals directly in Java source code files, but you need to tell the compiler that the file is in UTF-8 (javac -encoding UTF-8)

String x = "漢字";

如果你想疯狂，你甚至可以在方法，变量或类名中使用中文字符。但这是违反命名约定的，我强烈反对它至少对于类名称（因为它们需要映射到文件名，Unicode可能会导致问题）：

If you want to go wild, you can even use Chinese characters in method, variable, or class names. But that is against the naming conventions, and I would strongly discourage it at least for class names (because they need to be mapped to file names, and Unicode can cause problems there):

結果 漢字　= new 物().処理();
