C：和C之间的区别：/ [英] Difference between C: and C:/

问题描述

我刚刚阅读了一些java书并制作了一些小程序用于练习，我创建了一个小代码来获取有关我输入的路径的信息，代码是：

I was just reading some java book and making some small programs for practice, I created a small code to get information about the path I entered, and the code is:

String path = JOptionPane.showInputDialog("Enter Path to analyze");

File file =  new File(path);

if (file.exists())
{
    String result = "";
    if (file.isDirectory())
    {
        result += "Path is directory\n ";
        String [] resList = file.list();

        for (String s : resList)
        {
            result += s + ", ";
        }
    }
    if (file.isFile())
    {
        result += "Path is a file\n";
    }

    JOptionPane.showMessageDialog(null, result);

现在在输入对话框中，当我输入 C：，结果是 build，build.xml，manifest.mf，nbproject，src ，但是当我输入C：/时，它显示了完整的目录列表和C中的文件。

Now in the input dialogue, when I enter C:, the result is build, build.xml, manifest.mf, nbproject, src, but when I enter C:/, it shows the complete list of directories and files in C.

奇怪的是，D驱动器和其他驱动器不会发生这种情况（即D：/和D :)结果相同，发生了什么请解释一下？

And strangely it does not happen with the D drive and other drives (i.e. the result is same for D:/ and D:), what is happening please explain?

更新
使用C＃在WPF中也是如此！

Update Same happens in WPF using C#!

推荐答案

C：表示当前在驱动器上选择的目录 C：。在您的情况下，它可能是您的应用程序运行的目录。

C: means "whatever directory is currently selected on drive C:". In your case, it's probably the directory that your application is running from.

D：与 D：/ 在您的情况下，因为根目录 中的当前工作目录D： 。

D: is the same as D:/ in your case because the root directory is the current working directory in D:.
