Why to use serialization in Java? By: Rajesh P.S.Serialization is a mechanism used when there is a need to persist object state by converting it into a byte stream. During runtime, all objects of an application reside in memory (heap memory), and when the application terminates, the ...
or can be sent through streams. The reverse process of creating object from sequence of bytes is called deserialization A class must implement Serializable interface present in java,io package in order to serialize its object successfully. Serializable is a marker interface that adds serializable behav...
Object Deserialization Object Serialization The process of reading and writing objects in a file is called object serialization. In Java, serialization occurs automatically. An object is serialised using the following steps: 1. Create a FileOutputStream to write to a file (say, object.dat) and wr...

import java.io.ObjectOutputStream; import java.io.Serializable; public class Demo { public static void main(String[] args) throws IOException, ClassNotFoundException { Student student = new Student("Justin", 8.51, 101, true); System.out.println("Before Deserialization:"); ...
serialVersionUID 是用于保证同一个对象(在序列化中会被用到)可以在Deserialization过程中被载入。serialVersionUID 是用于对象的版本控制。你可以参考serialVersionUID in java serialization获取更多信息。 对于序列化: 步骤如下: 让我们看一个列子: 在src->org.arpit.javapostsforlearning 创建Employee.java ...

Example : Deserialization of Object in JavaTo deserialize the object, we are using ObjectInputStream class that will read the object from the specified file. See the below example.import java.io.*; class Studentinfo implements Serializable { String name; int rid; static String contact; Student...
One of the fundamental strength of Java is its serialization mechanism. This is basically serialization of Java objects, where the object is persisted as a sequence of bytes. The persistent storage can be file system, database or streams. And, deserialization is just the reverse process, where ...
