JFileChooser - File save as

Question

Hi,
I have a method in my application called "export" which exports the JPanel content into a file.
I used the JFileChooser to let the users choose their desired location for saving the file.
The problem is unless user explicitly types in the file format, it saves the file with no extension.
How can I have formats like jpg, png in the File Type drop down menu.
The code is on a different computer, so dont worry about syntax errors, I just write the important bits:
JFileChooser jfc = new JFileChooser();
int answer = jfc.showSaveDialog(this);
if(answer==jfc.APPROVE_OPTION) {
   try {
      File file = jfc.getSelectedFile();
      ImageIO.write(Graph, "png", file); //Graph is what that needs to be exported 
   } catch () {}any help, highly appreciated, thanks

still got the problem,
I implemented the FileFilter and its two methods, but what I get in the menu is the string i used in the getDescription method.Yeah, that's what the description is meant for.
what if i want to include more than one extension?Add more filters.
Also, even if I choose that as the file type, it still saves it with no extension. Do I need to get the string from the menu and add it
manually to the end of file name?Yes, of course. (That is, you get the selected filter, determine the appropriate extension and add it, if the user did not explicitly specify an extension.)
