I already have a method which export data as a csv. No I need to implement an export as a xml and as a java object itself.
So I need to know, as what the user will save it. I want to find out what extention he insert in the already made JFileChooser.
Here's the code I already have:
JFileChooser chooser = new JFileChooser();
int opt = chooser.showSaveDialog(frame);
if (opt != JFileChooser.APPROVE_OPTION)
return;
try {
File file = chooser.getSelectedFile();
export(file);
JOptionPane.showMessageDialog(frame, file,
getText("message.filesaved"),
JOptionPane.INFORMATION_MESSAGE);
} catch (Exception e) {
JOptionPane.showMessageDialog(frame, e.getMessage(),
getText("message.error"), JOptionPane.ERROR_MESSAGE);
}
So how can I extend this method to allow the user, to choose if he will export it as a csv (already done), xml or java object?
What I already tried:
I tried to use the FileNameExtensionFilter
to add a CSV option, a XML option or a Java Object option. But with this method, I can't find out which one the user took.
