كيف احول object الى byte array في جافا

private static byte[] objectToBytes(Object object) throws IOException {


    try (ByteArrayOutputStream bos = new ByteArrayOutputStream();

         ObjectOutput out = new ObjectOutputStream(bos)) {

        out.writeObject(object);

        return bos.toByteArray();

    }

}


private static Object bytesToObject(byte[] bytes) throws IOException, ClassNotFoundException {

    try (ByteArrayInputStream bis = new ByteArrayInputStream(bytes);

         ObjectInput in = new ObjectInputStream(bis)) {

        return in.readObject();

    }

}

لكن انتظر لحضة عليك ان تقوم ب وراثة Serializable interface, مثلاً:

class User implements Serializable{
String name;

User(String name) {

    this.name = name;

}

}
