value = 66;
}
}

public class Test extends Big implements Serializable {
private static final long serialVersionUID = 1L;

public static void main(String[] args) {
Test ts = new Test();
ts.value = 11;
try {
FileOutputStream fos = new FileOutputStream("savedata.ser");
ObjectOutputStream os = new ObjectOutputStream(fos);
os.writeObject(ts);
os.close();
FileInputStream fs = new FileInputStream("savedata.ser");
ObjectInputStream is = new ObjectInputStream(fs);
Test ts2 = (Test) is.readObject();
System.out.print(ts2.value);
is.close();
} catch (Exception x) {
}}}
