I have a Java program that creates a file and prints a bunch of data using this statement:
我有一个Java程序，它创建一个文件并用这个语句打印大量数据:
out.write(data+"|"+data2+"\r\n");
When I view this file in vim in Unix I see a ^M after each line. What is it? What is causing this? How can I get rid of it?
当我查看这个文件在vim在Unix中每一行后,我看到一个^ M。它是什么?是什么原因导致了晒伤的?我怎么才能摆脱它呢?

^M is character 13 (decimal) which is the carriage return (in your code it's \r). Notice that M is the 13th letter of the alphabet.
^ M是字符13(十进制)这是回车(在代码\ r)。注意M是字母表中的第13个字母。
You can get rid of it by not including \r in your code. This will work fine if you're on a unix platform. On windows, the file will look funny unless you're viewing it in something like Wordpad.
您可以通过在代码中不包含\r来摆脱它。如果您使用的是unix平台，这将很好地工作。在windows上，这个文件看起来很有趣，除非你在记事本上看到它。

You need to use the platform-specific line separator string instead of \r\n when constructing your output string. That can be obtained by System.getProperty("line.separator");.
在构建输出字符串时，需要使用特定于平台的行分隔符字符串，而不是\r\n。可以通过System.getProperty(“line.separator”)获得。

*nix uses \n for newline, Windows uses \r\n and produces that ^M character in vi and the like.
* nix使用\ n换行,Windows使用\ r \ n和M ^字符产生在vi中等等。

You may want to try running the file through dos2unix utility in *nix, it will get rid of ^M
你可能想要尝试运行文件通过在* nix dos2unix实用程序,它将摆脱^ M

You'll generally only see those if the first line was a unix line ending (lf) but it also includes DOS line endings. To remove them (and correct the file), load it again using :e ++ff=dos, then :set ff=unix, then write it.
通常，只有当第一行是unix行结束符(lf)时，您才会看到这些内容，但它也包括DOS行结束符。要删除它们(并修改文件)，请再次使用:e ++ff=dos加载它，然后:set ff=unix，然后编写它。
Within the Java code, if you're writing text data instead of binary, use a PrintStream and use print() and println() which adds the correct line ending for your system.
在Java代码中，如果您正在编写文本数据而不是二进制数据，请使用PrintStream并使用print()和println()，这将为您的系统添加正确的行尾。
