mac java 创建文件夹,Java:如何在Mac OS X中创建新文件夹

I want to create a folder in ex. my desktop in Mac OS X

I try to use this code, instead of Mymac is my name of course:)

String path="/Users/Mymac/Desktop";

String house = "My_home";

File file=new File(path);

if(!file.exists())

file.mkdirs(); // or file.mkdir()

file=new File(path + "/" + house);

try {

if(file.createNewFile())

{

}

} catch (IOException ex) {

ex.printStackTrace();

}

Do you know how I could create a new folder?

And another thing is when I want to create a folder in the directory where my code is, do you know how I could write that? I have tried

String path="./";

String path="::MyVolume";

String path=".";

解决方案

To find the folder/directory where one of your classes is (assuming they are not in a Jar), and then to create a subfolder there:

String resource = MyClass.class.getName().replace(".", File.separator) + ".class";

URL fileURL = ClassLoader.getSystemClassLoader().getResource(resource);

String path = new File(fileURL.toURI()).getParent();

String mySubFolder = "subFolder";

File newDir = new File(path + File.separator + mySubFolder);

boolean success = newDir.mkdir();

(The code above could be made more compact, I listed it more verbosely to demonstrate all the steps.) Of course, you need to be concerned about permission issues. Make sure that the user which is running java has permission to create a new folder.
