What is difference between shallow copy and deep copy? Which is default?..

Answer / hrpynux@gmail.com

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.
