One method of copying an object is the shallow copy. In that case a new object B is created, and the field’s values of A are copied over to B. Default behavior when cloning an object is to perform a shallow copy of the object's fields. In that case, both the original object and the cloned object, hold references to the same objects.
//Shallow Copy Object Cloning in Java /* class Designation { String role; @Override public String toString() { return role; } } class Employee implements Cloneable { String name; int age; Designation deg=new Designation(); public void display() { System.out.println("Name : "+name); System.out.println("Age : "+age); System.out.println("Department : "+deg); System.out.println("----------------------"); } public Object clone() throws CloneNotSupportedException { return super.clone(); } } public class objectCloningDemo { public static void main(String[] args) throws CloneNotSupportedException { Employee e1 =new Employee(); e1.name="Ram Kumar"; e1.age=25; e1.deg.role="Manager"; System.out.println("Before Changing Role : "); e1.display(); System.out.println("Cloning and Printing E2 object : "); Employee e2 = (Employee)e1.clone(); e2.deg.role="HR"; e2.display(); System.out.println("After Changing Role : "); e1.display(); } } */
