Java shallow clone and deep clone

Concept: The slang is to copy a copy

General implementation:

Implementing the Cloneable Interface Override Clone () method

Part of the Code

Public Object Clone () {
Object o = null;
try {
o = (Student) super.clone ();//Clone () in object identifies which one you want to copy
An object.
} catch (Clonenotsupportedexception e) {
System.out.println (E.tostring ());
}
return o;
}

Note: Shallow copy cannot copy references at the same time

If you need to copy a reference, the object you want to reference is also cloned to do a deep copy

A better approach is to use serialization (often-called serialization) for deep replication (no need to implement cloneable interface, need to implement Serializable interface)

See part of the code

Public Object Deepclone () throws IOException, Optionaldataexception,
classnotfoundexception {
Write an object into the stream
Bytearrayoutputstream bo = new Bytearrayoutputstream ();
ObjectOutputStream oo = new ObjectOutputStream (bo);
Oo.writeobject (this);
Read it from the stream.
Bytearrayinputstream bi = new Bytearrayinputstream (Bo.tobytearray ());
ObjectInputStream oi = new ObjectInputStream (BI);
Return (Oi.readobject ());
}
