I have a problem:

I copied more value (for example 23700 5000.2 0.000) from Excel file in a file .txt.

When I read in java this value stored in .txt file, and i copy this in another file .txt (with java), the result is the same:

【问题讨论】：

I suggest you read the Excel file as an excel file. e.g. use the POI API
There is no text but encoded text. Not knowing the character set and encoding of a ".txt" file is data loss. When you do know, you specify it in your file/stream/whatever reader (usually, it's an argument to the constructor.)

【解决方案1】：

了解今天，文本文件并不全是 ascii。它们可以是 utf-8、latin-1、utf-16 等

问题可能是您在复制时打开的文本文件格式错误，或者写入的文本格式错误。要正确打开，请使用

InputStreamReader reader = new InputStreamReader(new FileInputStream(file),"utf-16");

将您的文件格式替换为 utf-16

对于写作，在FileOutputStream 上使用OutputStreamWriter

我在想有一天文本文件是 ASCII。在带有 RSX-11 操作系统的 Digital Equipment Corp PDP-11 上，我想他们可能是这样。（我没有在 APL 中编程。）在我的 Corona Data Systems IBM 兼容 PC 上使用 MS-DOS 1.25，它们是 CP 437。╟画框字符当时真的很热╢（我们今天仍然在 Windows 中使用它们@987654324 @)
