How to clone object via Serialization 

Jodd is an open-source java library with lot of reusable components and feature rich utilities. This requires the library jodd-3.3.2.jar to be in classpath. The following example shows how to use ObjectUtil.cloneViaSerialization() API. It creates a deep copy of the given object.

package com.bethecoder.tutorials.jodd.common;

public class Student implements java.io.Serializable {

  private static final long serialVersionUID = -5962595557796049374L;
  private String name;
  private int age;
  private String hobby;

  public Student() {
  }

  public Student(String name, int age, String hobby) {
    super();
    this.name = name;
    this.age = age;
    this.hobby = hobby;
  }

  public String getName() {
    return name;
  }
  public void setName(String name) {
    this.name = name;
  }
  public int getAge() {
    return age;
  }
  public void setAge(int age) {
    this.age = age;
  }
  public String getHobby() {
    return hobby;
  }
  public void setHobby(String hobby) {
    this.hobby = hobby;
  }
  
  public String toString() {
    return "Student[name = " + name + ", age = " + age + ", hobby = " + hobby + "]";
  }
}

package com.bethecoder.tutorials.jodd.encode;

import java.io.IOException;

import jodd.util.ObjectUtil;

import com.bethecoder.tutorials.jodd.common.Student;

public class ObjectCloneTest {

  /**
   @param args
   @throws ClassNotFoundException 
   @throws IOException 
   */
  public static void main(String[] argsthrows IOException, ClassNotFoundException {
    Student std = new Student("Sriram"2"Chess");
    Student std2 = (StudentObjectUtil.cloneViaSerialization(std);
    
    System.out.println(std);
    System.out.println(std2);
    
    System.out.println(std.hashCode());
    System.out.println(std2.hashCode());
  }

}
   

It gives the following output,
Student[name = Sriram, age = 2, hobby = Chess]
Student[name = Sriram, age = 2, hobby = Chess]
