Can an interface implement Serializable?

Can an interface implement Serializable?

Yes, you can extend the Serializable interface. If you do, all classes that implement the new subinterface will also be implementing Serializable .

Why do we implement Serializable interface in Java?

Implement the Serializable interface when you want to be able to convert an instance of a class into a series of bytes or when you think that a Serializable object might reference an instance of your class. Serializable classes are useful when you want to persist instances of them or send them over a wire.

How can we implement Serializable interface?

The Serializable interface must be implemented by the class whose object needs to be persisted. The String class and all the wrapper classes implement the java. io. Serializable interface by default.

What is implements Serializable 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.

Can Java interface be Serializable?

The Serializable interface is present in java.io package. It is a marker interface. A Marker Interface does not have any methods and fields. Thus classes implementing it do not have to implement any methods.

Is Serializable 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 will happen if we don’t implement serializable?

What happens if you try to send non-serialized Object over network? When traversing a graph, an object may be encountered that does not support the Serializable interface. In this case the NotSerializableException will be thrown and will identify the class of the non-serializable object.

Why do we serialize objects?

Serialization is the process of converting an object into a stream so that it can be saved in any physical file like (XML) or can be saved in Database. The main purpose of Serialization in C# is to persist an object and save it in any specified storage medium like stream, physical file or DataBase.

What is Serializable interface in Java with example?

Serialization is a mechanism of converting the state of an object into a byte stream. Serialization is done using ObjectOutputStream. 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.

How do you make an object Serializable in Java?

To make a Java object serializable you implement the java. io. Serializable interface. This is only a marker interface which tells the Java platform that the object is serializable.

What is serialize interface?

The Serializable interface is present in java.io package. It is a marker interface. A Marker Interface does not have any methods and fields. Thus classes implementing it do not have to implement any methods. Classes implement it if they want their instances to be Serialized or Deserialized.

Is serializable a functional interface?
