Java / Object, Class and Package

Difference between shallow and deep copy in Java.

Shallow copy.	Deep copy.
Cloned Object and the original object are not 100% disjoint.	Cloned Object and original object are 100% disjoint.
Any changes to the cloned object will be reflected in original object or vice versa.	Changes made to cloned object won't be reflected to original object or vice versa.
Default version of clone method creates the shallow copy of an object.	To create the deep copy of an object, you have to override clone method.
Shallow copy is preferred if an object has only primitive fields.	Deep copy is preferred if an object has references to other objects as fields.
Shallow copy is fast and cost effective.	Deep copy is slow and very expensive.
