Mac 和 Windows 上存储文件的常见位置

发布于 2024-09-24 06:49:10 字数 233 浏览 5 评论 0原文

我正在编写一个需要保存文件的java代码。

以下代码适用于 Mac。

ImageIO.write(movie_image, "jpg",new File("/Users/sathyap/Desktop/movieimages/"+文件名+".jpg"));

有没有办法可以给出目录结构“/Users/sathyap/Desktop/movieimages/” 硬编码适用于 Mac 和 Windows。

假设该程序在 Mac 和 Windows 中的目录 (X) 下运行。您可以这样编码：

//This will give the current working directory
String directoryPath = System.getProperty("user.dir");

//now get the platform dependent path
String filePath = directoryPath + File.separator + "data" + File.separator + "filename";

File fileToWriteTo = new File(filePath);

File.separator 将处理平台...您的文件将始终保存在当前工作目录下...您可以提供访问这些路径的快捷方式并将它们放在桌面上

如果用户可以执行写入该目录的程序...我假设用户也可以毫无问题地访问这些文件

Assuming that the program runs under a directory (X) in either Mac and Windows. You can code it like this:

//This will give the current working directory
String directoryPath = System.getProperty("user.dir");

//now get the platform dependent path
String filePath = directoryPath + File.separator + "data" + File.separator + "filename";

File fileToWriteTo = new File(filePath);

File.separator will take care of platform ... your files will always be saved under current working direcoty ... you can provide shortcuts to access those paths and place them on desktop

If a user can execute the program that writes to that directory ... I will assume that the user can also access the files without problem

编辑：完全改变我的答案，因为我认为您正在寻找的是坚持跨平台而不是分别针对每种情况进行编码。

System.getProperty("user.home")

EDIT: Totally changing my answer because I think what you're looking for is sticking to cross-platform rather than coding for each situation separately.
