Creating and writing to a file with UTF-8 encoding
提问by Kraken
Here is my Java code.
这是我的 Java 代码。
File file = new File(path);
StringWriter sw = new StringWriter();
//Do something.
out.println(sw.toString()); //Works fine; prints.
try {
FileUtils.writeStringToFile(file, sw.toString(), "UTF-8");
} catch (IOException e) {
throw new RuntimeException( e );
}
I don't already have the file created, and neither is it creating it after the execution. How can I do this?
我还没有创建文件，也没有在执行后创建它。我怎样才能做到这一点？

See File.createNewFile().
Atomically creates a new, empty filenamed by this abstract pathname if and only if a file with this name does not yet exist. ..
当且仅当具有此名称的文件尚不存在时，以原子方式创建以该抽象路径名命名的新的空文件。..
As mentioned by @JohnWatts in comments:
正如@JohnWatts 在评论中提到的：
..both
PrintWriterand your code create the file, but pre-1.3FileUtils.writeStringToFiledoes not.
..both
PrintWriter和您的代码都会创建文件，但 1.3 之前的版本FileUtils.writeStringToFile不会。

Don't use StringWriter, use PrintWriterinstead:
不要使用StringWriter，PrintWriter而是使用：
PrintWriter w = new PrintWriter(file);
w.print(string);
w.flush();
w.close()

I checked the code and it works.
I checked the code and it works.
The only problem that I could think of is pathvalue. Try with hardcoded path value. Because I doubt file is getting created and you are not able to find it.
我能想到的唯一问题是path价值。尝试使用硬编码的路径值。因为我怀疑文件正在创建并且您无法找到它。
