How to change JFileChooser start directory to desktop?
提问by lnk
I want to change JFileChooserstart directory to desktop. So, in my computer I wrote:
我想将JFileChooser开始目录更改为桌面。所以，在我的电脑上，我写道：
JFileChooser fc = new JFileChooser("C:\Users\LNK\Desktop");
The problem is, when I compile my code and run program in another computer it doesn't work because there are no C:\\Users\\LNK\\Desktoppath. So, is there some kind of "apsolute" path of desktop?
问题是，当我编译我的代码并在另一台计算机上运行程序时，它不起作用，因为没有C:\\Users\\LNK\\Desktop路径。那么，是否有某种“绝对”的桌面路径？

You can use a user.homesystem property to get user directory.
So your code would look like
您可以使用user.home系统属性来获取用户目录。所以你的代码看起来像
String userDir = System.getProperty("user.home");
JFileChooser fc = new JFileChooser(userDir +"/Desktop");

Here is another option for getting to the Windows desktop:
这是进入 Windows 桌面的另一种选择：
fileChooser.setCurrentDirectory(new File("C:\"));
Action details = fileChooser.getActionMap().get("Go Up");
details.actionPerformed(null);
details.actionPerformed(null);
If you leave off the last line, you will get to "Computer"
如果你离开最后一行，你将进入“计算机”
