To save the information in a Form/Dialog when you exit the Swing Application.
Make your form class implement java.io.Serializable
To save the form:
See http://exampledepot.com/egs/java.io/SerializeObj.html
To read the form:
http://exampledepot.com/egs/java.io/DeserializeObj.html?l=rel
To save (using a different filename of each saved form):
object = instance of the form to save
   try {
        // Serialize to a file
        ObjectOutput out = new ObjectOutputStream(new FileOutputStream("filename.ser"));
        out.writeObject(object);
        out.close();
    } catch (IOException e) {
    }To read back
Object obj;
try {
        // Deserialize from a file
        File file = new File("filename.ser");
        ObjectInputStream in = new ObjectInputStream(new FileInputStream(file));
        // Deserialize the object
        obj = in.readObject();
        in.close();
    } catch (ClassNotFoundException e) {
    } catch (IOException e) {
if (obj instanceof 'your form's class') {
// Cast it to the correct class and away you go
}
