JFileChooser & data saver error
Hi there,
I use
publicvoid savePlayers(){
try{
BufferedWriter bufferedWriter =new BufferedWriter(new FileWriter(new File("Filename.txt")));
for (int i = 0; i < table.getModel().getRowCount(); i++){
bufferedWriter.write((String) table.getValueAt(i, 0) +"|" +
(String) table.getValueAt(i, 1) +"|" +
(Integer) table.getValueAt(i, 2) +"|");
}
bufferedWriter.close();
}catch (Exception e){
e.printStackTrace();
}
}
to save my table into a txt file.
now im trying to make this work with a filechooser and I made
if (source.getSource() == (JButton) cmdSave){
JFileChooser fcs =new JFileChooser(new File("Sporters.txt"));
fcs.addChoosableFileFilter(new MyFilter());
fcs.showSaveDialog(frame);
File file2 = fcs.getSelectedFile();
savePlayers();
}
to do so.
MyFilter is just a filter filtering all *.txt files to be seen only.
Now when I try to use savePlayers and change "Filename.txt" to file2.getName() it gives me an error
//error code:

What could can be the problem? What should I use instead of filename.txt/file2.getName()
or is the problem somewhere else?
