General Path To Downloads Folder
提问by user3243242
I have a DownloadTask class in java that takes a filename and URL, downloads that file and saves it to the downloads folder.
我在 Java 中有一个 DownloadTask 类，它采用文件名和 URL，下载该文件并将其保存到下载文件夹中。
To save it to mydownloads folder, I have the line
要将其保存到我的下载文件夹中，我有一行
File file = new File("/users/myName/Downloads" + fileName + ".txt");
File file = new File("/users/myName/Downloads" + fileName + ".txt");
What can I replace this path with so that anyone can run the program and the file will be saved to theirdownloads folder?
我可以用什么替换此路径，以便任何人都可以运行该程序并将文件保存到他们的下载文件夹中？

Your own folder is accessible using the $HOME environment variable.
您可以使用 $HOME 环境变量访问您自己的文件夹。
In Java, you can find you home folder using the user.homesystem property. See Java system properties.
在 Java 中，您可以使用user.home系统属性找到您的主文件夹。请参阅Java 系统属性。
e.g.:
例如：
System.getProperty("user.home");
