What is serialization process in Java?
To serialize an object means to convert its state to a byte stream so that the byte stream can be reverted back into a copy of the object. A Java object is serializable if its class or any of its superclasses implements either the java. io. Serializable interface or its subinterface, java.

How do you serialize and deserialize a list?
Here is a complete example. These are the steps:
- Create Class Item() which implements Serializable.
- In Main – Create 2 Item Objects.
- Add it to ArrayList.
- Serialize the ArrayList. Checkout file to see bytestream of an Object. (Below image)
- Deserialize the bytestream from the same file to see Object.
Why Serialisation is used in Java?
Deserialization is the reverse process where the byte stream is used to recreate the actual Java object in memory. This mechanism is used to persist the object. The byte stream created is platform independent. So, the object serialized on one platform can be deserialized on a different platform.
What is serialization and explain how its process?
Serialization is the process of converting a data object—a combination of code and data represented within a region of data storage—into a series of bytes that saves the state of the object in an easily transmittable form.
What is the advantage of serialization?
Serialization allows us to transfer objects through a network by converting it into a byte stream. It also helps in preserving the state of the object. Deserialization requires less time to create an object than an actual object created from a class. hence serialization saves time.
What are different methods in serialization in Java?
Serialization in Java is a mechanism of writing the state of an object into a byte-stream. It is mainly used in Hibernate, RMI, JPA, EJB and JMS technologies….Important Methods.
| Method | Description |
|---|---|
| 1) public final Object readObject() throws IOException, ClassNotFoundException{} | It reads an object from the input stream. |
How many ways we can serialize in Java?
Java Serialization Methods That’s why there are four methods that we can provide in the class to change the serialization behavior.
How many methods Serializable has?
How many methods Serializable has? Explanation: Serializable interface does not have any method. It is also called a marker interface. 5.
Why serializable interface is used in Java?
Serializable is a marker interface (has no data member and method). It is used to “mark” Java classes so that the objects of these classes may get a certain capability. The Cloneable and Remote are also marker interfaces. The Serializable interface must be implemented by the class whose object needs to be persisted.
What is deserialization and serialization in Java?
Serialization in Java is a mechanism of writing the state of an object into a byte stream. It is mainly used in Hibernate, RMI, JPA, EJB and JMS technologies. The reverse operation of serialization is called deserialization.
What are the rules for serialization of an object?
Note: All the objects within an object must be Serializable. If there is any static data member in a class, it will not be serialized because static is the part of class not object. Rule: In case of array or collection, all the objects of array or collection must be serializable.
How to implement serialization with inheritance in Java?
Java Serialization with Inheritance (IS-A Relationship) 1 import java.io.Serializable; 2 class Person implements Serializable {. 3 int id; 4 String name; 5 Person (int id, String name) {. 6 this.id = id; 7 this.name = name; 8 class Student extends Person {.
