Clonable Object example

With this example we are going to demonstrate how to create a cloneable object of a class. In short, to create a cloneable object of a class, we have created a class that implements the Cloneable interface, so that it can use the clone() method to create cloneable objects, as described in the following steps:

  • We have created a class Person, that implements the Cloneable interface. It has two String fields.
  • The class overrides the clone() method of Object, where it creates a clone Person object, sets the fields of the clone object to the ones of the original one, and returns the clone object. It also has getters and setters for its fields. 
  • We create a new Person object and then use the clone() method to get its clone, then use the clone() method to get a clone of the clone.

Let’s take a look at the code snippet that follows:  

package com.javacodegeeks.snippets.core;

public class ClonableClass {

    public static void main(String[] args) {

  Person person1 = new Person();



  Person person2 = (Person) person1.clone();

  Person person3 = (Person) person2.clone();

  System.out.println("Person 1: " + person1.getFN() + " " + person1.getLN());

  System.out.println("Person 2: " + person2.getFN() + " " + person2.getLN());

  System.out.println("Person 3: " + person3.getFN() + " " + person3.getLN());

class Person implements Cloneable {

    private String fn;
    private String ln;

    public Object clone() {

  Person object = new Person();



  return object;

    public String getFN() {

  return fn;

    public void setFN(String firstName) {

  this.fn = firstName;

    public String getLN() {

  return ln;

    public void setLN(String lastName) {

  this.ln = lastName;


Person 1: F L
Person 2: F L
Person 3: F L

This was an example of how to create a cloneable object of a class in Java.
