Storing data in tablemodel to a binary file

Question

hi,
i have a program that uses AbstractTableModel with Jtable....I need to store data in a file when the program closes... i heard that there is a way to some how convert data in Tablemodel to a binary file and retrieve data from the binary file...other then storing it in a text file and parsing the data. So can anyone help me?
Thanks

You can loop through the data in the table and Serialize the data using object serialization.
Simply implement the java.io.Serializable interface. Then use this code for serizlizing the data. Note that to serialize data, it must be an object not primitive types.
serialize to a binary file
try
    ObjectOutputStream os = new ObjectOutputStream(new FileOutputStream(new File("datastore.ser")));
    os.writeObject(<your data from table>);
    os.flush();
catch (IOException ioe) { ioe.printStackTrace(); }
reconstructing the object from binary file
try
    ObjectInputStream is = new ObjectInputStream(new FileInputStream(new File("datastore.ser")));
    obj = (<data type of Object>) is.readObject();
catch (IOException ioe)
    ioe.printStackTrace();
}Hope this helps,
