How to do deep cloning using in memory serialization in java - How To Do In Java

that easiest way of deep cloning (with some performance overhead) is Serialization. It involves serializing the object to bytes and from bytes to object again.

 public SerializableClass deepCopy() throws Exception

    {

        //Serialization of object

        ByteArrayOutputStream bos = new ByteArrayOutputStream();

        ObjectOutputStream out = new ObjectOutputStream(bos);

        out.writeObject(this);

 

        //De-serialization of object

        ByteArrayInputStream bis = new   ByteArrayInputStream(bos.toByteArray());

        ObjectInputStream in = new ObjectInputStream(bis);

        SerializableClass copied = (SerializableClass) in.readObject();

 

        //Verify that object is not corrupt

 

        //validateNameParts(fName);

        //validateNameParts(lName);

 

        return copied;

    }
