Answer / saravanan sagadevan
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

Java uses clone() of Object class to copy content of 1
object to other object. Classes can implement Cloneable
Interface to override clone() method of object class.
The following sample code will show the procedure for
implementing cloneable interface.
public class CloneExp implements Cloneable {
private String name;
private String address;
private int age;
private Department depart;
public CloneExp(){
}
public CloneExp(String aName, int aAge, Department aDepart) {
this.name = aName;
this.age = aAge;
this.depart = aDepart;
}
protected Object clone() throws CloneNotSupportedException {
CloneExp clone=(CloneExp)super.clone();
// make the shallow copy of the object of type Department
clone.depart=(Department)depart.clone();
return clone;
}
public static void main(String[] args) {
CloneExp ce=new CloneExp();
try {
// make deep copy of the object of type CloneExp
CloneExp cloned=(CloneExp)ce.clone();
} catch (CloneNotSupportedException e) {
e.printStackTrace();
}
}
}

Answer / sunil kumar
Cloneable is a marker interface present in java.lang package. If we want to copy the object then we are using clone method by implementing our class from Cloneable interface.
