What is Serializable interface?
Serializable interface. 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.
What is serialization in language?
Serialization or marshaling is the process of converting object state into a format that can be transmitted or stored. The serialization changes the object state into series of bits. The object state could be reconstructed later in the opposite process, called deserialization or unmarshalling .
Why Serializable is an interface?
That Serializable is a marker interface means that it contains no methods. Therefore, a class implementing Serializable does not have to implement any specific methods. Implementing Serializable thus just tells the Java serialization classes that this class is intended for object serialization.
What does Serializable mean in programming?
Serialization is the process of converting an object into a stream of bytes to store the object or transmit it to memory, a database, or a file. Its main purpose is to save the state of an object in order to be able to recreate it when needed. The reverse process is called deserialization.
What does Serializable mean 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.
What are the methods in Serializable interface?
Serializable doesn’t contain any method, it’s the ObjectOutputStream and ObjectInputStream classes that can do that work, through the writeObject and readObject methods. Serializable is just a marker interface, in other words it just puts a flag, without requiring any fields or methods.
Is Serializable interface a functional interface?
Serializable is a bit of a unique interface in this regards, as there is nothing you actually need to implement. Without making this cast, the lambda will be considered unserializable, which does not make Kryo happy.
What is serialization with example?
Serialization is a mechanism of converting the state of an object into a byte stream. 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.
What is the meaning of Serializable?

How to serialize an object using an iserializable interface?
To serialize objects issued from this class, we should implement the ISerializable interface; this last one has a method ISerializable.GetObjectData that it should be implemented. This is how to implement the ISerializable interface: public class Person:ISerializable. {. private string _FirstName; private string _LastName;
What is the use of clonable,and Serializable interface?
A serializable interface is used to persist an object. The cloneable interface is used to clone the class objects. Both these interfaces are marker interfaces i.e. they are empty. But when a class implements them, then they indicate that the compiler can expect some special behavior from the classes implementing them.
Which classes must implement the Serializable interface?
The try/catch block tries to catch a ClassNotFoundException,which is declared by the readObject () method.
