clonable interface is a marker interface to clone the
object.If we want to clone the object then we have to
override clone method .

public Object clone() throws CloneNotSupportedException(){
try{
super.clone();
}catch(CloneNotSupportedException exe){


}
There are two types of clone 1. Shallow copy 2.Deep copy

1. Shallow Copy:
Default copy is shallow copy . Ex :

Class Person {
private Car car ;
public Car getCar(){
this.car=car
}
public Object clone() throws CloneNotSupportedException
(){
try{
super.clone();
}catch(CloneNotSupportedException exe){


}
When Person object is copied, new perosn object will be
created , but Member object car is shared by both copies.
If you make changes in Car object that will be reflected in
cloned object also.

Deep Copy:
===========
For Deep copy , seprate Parent(Person) and child object
will be created .There two copies will be created
