问题描述
使用Java:
我有一个 byte []
代表一个文件。
I have a byte[]
that represents a file.
如何将其写入文件(即 C:\ myfile.pdf
)
How do I write this to a file (ie. C:\myfile.pdf
)
我知道它已经完成了InputStream,但我似乎无法解决它。
I know it's done with InputStream, but I can't seem to work it out.
推荐答案
使用
FileUtils.writeByteArrayToFile(new File("pathname"), myByteArray)
或者,如果你坚持为自己工作......
Or, if you insist on making work for yourself...
try (FileOutputStream fos = new FileOutputStream("pathname")) {
fos.write(myByteArray);
//fos.close(); There is no more need for this line since you had created the instance of "fos" inside the try. And this will automatically close the OutputStream
}
