Usage

From source file:Data.java

public static void main(String[] args) {
    Data data = new Data(1);
    try {/* www. j a v  a  2 s. co m*/
        ObjectOutputStream objectOut = new ObjectOutputStream(
                new BufferedOutputStream(new FileOutputStream("C:/test.bin")));
        objectOut.writeObject(data);
        System.out.println("1st Object written has value: " + data.getValue());
        data.setValue(2);
        objectOut.writeObject(data);
        System.out.println("2nd Object written has value: " + data.getValue());
        data.setValue(3);
        objectOut.writeObject(data);
        System.out.println("3rd Object written has value: " + data.getValue());
        objectOut.close();
    } catch (IOException e) {
