Java Coding Problems

Cloning via serialization

This technique requires serializable objects (implement java.io.Serializable). Basically, the object is serialized (writeObject()) and deserialized (readObject()) in a new object. A helper method able to accomplish this is listed as follows:

private static <T> T cloneThroughSerialization(T t) {  try {    ByteArrayOutputStream baos = new ByteArrayOutputStream();    ObjectOutputStream oos = new ObjectOutputStream(baos);    oos.writeObject(t);    ByteArrayInputStream bais       = new ByteArrayInputStream(baos.toByteArray());    ObjectInputStream ois = new ObjectInputStream(bais);    return (T) ois.readObject();  } catch (IOException | ClassNotFoundException ex) {    // log exception    return t;  }}

So, the object is serialized in ObjectOutputStream ...
