I keep getting the error java.io.WriteAbortedException: writing aborted; java.io.NotSerializableException: java.io.FileOutputStream - serialization

Question

private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {
DefaultTableModel model = (DefaultTableModel) jTable1.getModel();
Vector<Vector> tableData = model.getDataVector();
//Saving of object in a file
try {
FileOutputStream file = new FileOutputStream("StudentFile.bin");
ObjectOutputStream output = new ObjectOutputStream(file);
// Method for serialization of object
output.writeObject(file);
output.close();
file.close();
} catch (Exception ex) {
ex.printStackTrace();
}
new ComputerScience_IA_UI().setVisible(true);
this.dispose();//to close the current jframe
}
this is my code
I wanted it to save data in a file
But every time it always gave me the same error java.io.WriteAbortedException: writing aborted; java.io.NotSerializableException: java.io.FileOutputStream

Answer 1

this is the right code
try {
FileInputStream file = new FileInputStream("StudentFile.bin");
ObjectInputStream input = new ObjectInputStream(file);
Vector<Vector> tableData = (Vector<Vector>)input.readObject();
input.close();
file.close();
DefaultTableModel model = (DefaultTableModel)jTable1.getModel();
for (int i = 0; i < tableData.size(); i++) {
Vector row = tableData.get(i);
model.addRow(new Object [] {row.get(0), row.get(1), row.get(2), row.get(3), row.get(4), row.get(5)});
}
} catch (Exception ex) {
ex.printStackTrace();
}
