public class Main {
  public static void main(String[] args) throws Exception {

    ObjectOutputStream out = new ObjectOutputStream(new BufferedOutputStream(
        new FileOutputStream("file.data")));
    out.writeBoolean(true);
    out.close();

    ObjectInputStream in = new ObjectInputStream(new BufferedInputStream(
        new FileInputStream("file.data")));

    byte[] byteArray = new byte[10];
    in.read(byteArray);
    System.out.println(Arrays.toString(byteArray));
    in.close();
