Saving and updating a single file

[AkisV]

Hey everyone.

I'm trying to make it possible to save program data into a single file in a way.

The problem is that I want to save multiple entries and load any one them at any time through my program but each time I save a new entry, instead of adding it as a second entry, it overwrites the existing one.

Here's my code:


private void SaveActionPerformed(java.awt.event.ActionEvent evt) {//GEN-FIRST:event_SaveActionPerformed
Vector<PointOnFret> vectorToSave = gPanel1.getFretPointsVector();
String chordName = JOptionPane.showInputDialog("Enter chord name");
Chord chordToSave = new Chord();
chordToSave.setName(chordName);
chordToSave.setPositions(vectorToSave);

try{
FileOutputStream fis = new FileOutputStream(FILENAME) ;
ObjectOutputStream out = new ObjectOutputStream(fis) ;
out.write(chordToSave);
out.flush();
out.close();
}


Can you see any problem?

Pls help

Read the API doc for the classes you are using to write a file. Some of them take an arg that says to APPEND the data to the file vs replacing the data in the file.
