In my previous post, I explained how to serialize an object to Byte Array. Below snippet is used to deserialize the byte array to java object.
/* De serialize the byte array to object */
private static Object getObject(byte[] byteArr) throws IOException, ClassNotFoundException {
ByteArrayInputStream bis = new ByteArrayInputStream(byteArr);
ObjectInput in = new ObjectInputStream(bis);
return in.readObject();
}
Find the below working application.
Employee.java
package com.sample.model;
import java.io.Serializable;
public class Employee implements Serializable {
private static final long serialVersionUID = 1L;
private int id;
private String name;
private String country;
public Employee(int id, String name, String country) {
super();
this.id = id;
this.name = name;
this.country = country;
}
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getCountry() {
return country;
}
public void setCountry(String country) {
this.country = country;
}
@Override
public String toString() {
return "Employee [id=" + id + ", name=" + name + ", country=" + country + "]";
}
}
Test.java
package com.sample.serialize;
import java.io.ByteArrayInputStream;
import java.io.ByteArrayOutputStream;
import java.io.IOException;
import java.io.ObjectInput;
import java.io.ObjectInputStream;
import java.io.ObjectOutputStream;
import com.sample.model.Employee;
public class Test {
/* Serialize the object to byte array */
private static byte[] getByteArray(Object obj) throws IOException {
ByteArrayOutputStream bos = new ByteArrayOutputStream();
try (ObjectOutputStream os = new ObjectOutputStream(bos)) {
os.writeObject(obj);
}
return bos.toByteArray();
}
/* De serialize the byte array to object */
private static Object getObject(byte[] byteArr) throws IOException, ClassNotFoundException {
ByteArrayInputStream bis = new ByteArrayInputStream(byteArr);
ObjectInput in = new ObjectInputStream(bis);
return in.readObject();
}
public static void main(String args[]) throws IOException, ClassNotFoundException {
Employee emp = new Employee(1, "Chamu", "India");
byte[] serializedData = getByteArray(emp);
Employee deserializedEmp = (Employee) getObject(serializedData);
System.out.println("Deserialized Employee : " + deserializedEmp);
}
}
Output
Deserialized Employee : Employee [id=1, name=Chamu, country=India]
