I need to use a JFileChooser in my simple Quiz game to load and save 'Question /Answer' sets , when the FileChooser window opens i want it to be in the current working directory, i want this to work in Linux,Windows and OSX, i am doubtful if the "user.dir" mehtod works in all platforms , Can someone help out , Code Below...

For loading 

public class openMenuItemListener implements ActionListener
{
public void actionPerformed(ActionEvent e)
{
nextButton.setEnabled(true);
JFileChooser fileChooser=new JFileChooser();
fileChooser.showOpenDialog(frame);
loadFile(fileChooser.getSelectedFile());
}
}

For Saving:

class saveMenuListener implements ActionListener
    {
    public void actionPerformed(ActionEvent e)
    {
    JFileChooser fileSave=new JFileChooser();
    fileSave.showSaveDialog(frame);
    saveFile(fileSave.getSelectedFile());

    }
    }//class ends

In those apps. the directory of the app. (where it is installed) is deliberately hidden from the app. itself. .. – Andrew Thompson Oct 20 '14 at 10:24
  • .. What form exactly are these quizzes stored in (text, HTML, serialized `String` objects..)? – Andrew Thompson Oct 20 '14 at 10:25
  • *"its working now thanks"* It's easy enough to get many things working on a single development machine. It is at time of deployment to anyone else that you'll then need to deal with problems like I was describing. But then, why is the app. offering a `JFileChooser` as opposed to simply a `JList` of available quizzes? Do you supply all the quizzes, or can the end user design new ones? – Andrew Thompson Oct 20 '14 at 10:34
  • @AndrewThompson I have two applicatios, a quiz builder to build a quiz ,save as text file , then load and play it from a quizplayer , its just a toy application I'm using as I'm learning java io,nothing much – Sainath S.R Oct 20 '14 at 10:42
  • @AndrewThompson I think you are mislead, i dont have any installers ,.jar files , web deployement etc , no need to access folders etc, i have just 2 .java Files which i run from the terminal ,Its that Simple!,Anyway thanks for the useful Hints – Sainath S.R Oct 20 '14 at 10:45

This gets you a `JFileChooser' referencing the current working directory (i.e. application startup location) on any system:

new JFileChooser(".");
