        String s = "Hello World!";

        try {

            FileOutputStream out = new FileOutputStream("test.txt");
            ObjectOutputStream oout = new ObjectOutputStream(out);

            // write something in the file
            oout.writeUTF(s);
            oout.writeUTF("This is an example");
            oout.flush();

            // create an ObjectInputStream for the file we created before
            ObjectInputStream ois = new ObjectInputStream(new FileInputStream("test.txt"));

            // skip 4 bytes and read the rest
            ois.skipBytes(4);
            for (int i = 0; i < ois.available() - 4; i++) {
                System.out.print("" + (char) ois.readByte());
            }
        } catch (Exception ex) {
            ex.printStackTrace();
        }
