AccessDeniedException on macOS (Java)

Question

我尝试创建一个目录，但我不断得到AccessDeniedException。我怎样才能进入?

代码:

String pathForMac = System.getProperty("user.home") + "Library\Application Support\Petatech\Zindroid";
Path macPath = Paths.get(pathForMac);{
if (!Files.exists(macPath)) {
    try {
        Files.createDirectory(macPath);
    } catch (Exception e) {
        System.out.println(e);
        JOptionPane.showMessageDialog(null, e.toString(), "Error", JOptionPane.ERROR_MESSAGE);
        }
    }
}

你可以使用特权块API来做到这一点。像这样的东西应该可以作为System工作。由于缺乏权限，getProperty(String key)可能会抛出AccessDeniedException。

String pathForMac = java.security.AccessController.doPrivileged(
    new java.security.PrivilegedAction<String>() {
        public String run() {
            return System.getProperty("user.home");
        }
    });
//Append the rest to the String
pathForMac += "Library\Application Support\Petatech\Zindroid";
