Java：如何阅读JFileChooser中的“文件类型”

Question

I want to create a new file while file type is choosing by the user on JFileChooser. How this is possible. I use this code for JFileChooser:

JFileChooser chooser = new JFileChooser();
chooser.setDialogTitle("Save data in your file format");

FileFilter type1 = new ExtensionFilter("Access 2007 Database(*.accdb)", ".accdb");
FileFilter type2 = new ExtensionFilter("Access 2002-2003 Database(*.mdb)", ".mdb");

chooser.addChoosableFileFilter(type1);
chooser.addChoosableFileFilter(type2);

int actionDialog = chooser.showSaveDialog(frame);

Now I an able to get the "File Name" when the user select any file by this code:

 chooser.getSelectedFile().getName();

But I dont know how to get "Files of type" when user select any file. For the convenience I also attach photo of JFileChooser:

You can get that information using JFileChooser .getFileFilter()

From the Javadocs :

Returns the currently selected file filter
