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();
}

}
}
