Saving files to a specific directory in Java?
提问by NSP
This is probably a silly question, but I'm pretty new to Java and I can't figure it out.
Basically, I'm trying to download some files from a website and I want to save them to a particular folder (rather than the default of the same folder that my Java file is located in). How can I do this?
这可能是一个愚蠢的问题，但我对 Java 很陌生，我无法弄清楚。
基本上，我试图从网站下载一些文件，我想将它们保存到特定文件夹（而不是我的 Java 文件所在的同一文件夹的默认文件夹）。我怎样才能做到这一点？
I've been using FileReader, BufferedReader, BufferedInputStream, and FileOutputStream classes.
我已经使用了FileReader，BufferedReader，BufferedInputStream，和FileOutputStream classes。
Thanks :)
谢谢 ：）

Java is pretty friendly with IO. Try something like this:
Java 对 IO 非常友好。尝试这样的事情：
File file = new File("/some/absolute/path/myfile.ext");
OutputStream out = new FileOutputStream(file);
// Write your data
out.close();
Notes:
笔记：
- Your program needs permission to write to the directory.
- If the first character of your path string is not
/, it will be relative to your "current" directory - If you're writing text, you might find a
BufferedWritereasier:BufferedWriter writer = new BufferedWriter(new FileWriter(file));. It hasnewLine()andwrite(String)methods
- 您的程序需要写入目录的权限。
- 如果您的路径字符串的第一个字符不是
/，它将相对于您的“当前”目录 - 如果您正在编写文本，您可能会发现一个
BufferedWriter更简单的方法：BufferedWriter writer = new BufferedWriter(new FileWriter(file));. 它有newLine()和write(String)方法

When you insantiate your FileOutputStreamyou can pass an absolute path to the constructor. Like this:
当您实例化时，您FileOutputStream可以将绝对路径传递给构造函数。像这样：
FileOutputStream os = new FileOutputStream("/path/to/file.txt");
回答by Akash Roy
FileOutputStream os = new FileOutputStream("//path//to//file.txt");
this will work as putting
这将作为把
//在一个
""将作为'/'。因为我们在地址栏中使用它。
