FileChooser仅从此文件夹获取getAttachement

How to make the user to select the file from only specified folder

如何让用户从指定的文件夹中选择文件

int returnVal = fc.showOpenDialog(FileChooser.this);

if (returnVal == JFileChooser.APPROVE_OPTION) {
    File file = fc.getSelectedFile();
    source = file.getAbsolutePath();
    fileName = file.getName();
    attachText.setText(fileName);
    source = source.replace("\\","\\\\");                
}

Here I will get the file from any folder, where I want the file only from G:\Project\Attachments. How Can i do this?

在这里,我将从任何文件夹中获取文件,我只想从G:\ Project \ Attachments获取文件。我怎样才能做到这一点?
