What is the use of serializable in Java?

Serialization in Java allows us to convert an Object to stream that we can send over the network or save it as file or store in DB for later usage. Deserialization is the process of converting Object stream to actual Java Object to be used in our program.

Is list serializable in Java?

List does not implement Serializable because is it not a key requirement for a list. There is no guarantee (or need) that every possible implementation of a List can be serialized. LinkedList and ArrayList choose to do so, but that is specific to their implementation.

What is the benefit of serialization in Java?

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.

Why do we need serialization ID in Java?

Simply put, the serialVersionUID is a unique identifier for Serializable classes. This is used during the deserialization of an object, to ensure that a loaded class is compatible with the serialized object. If no matching class is found, an InvalidClassException is thrown.

Can we serialize ArrayList in Java?

What is true serialization?

Serialization provides a way where an object can be represented as a sequence of bytes which includes the object’s data and information having the object’s type and the types of data stored in the object. It can only be read from the file after the serialized object is written into a file.

What is serialization in REST API?

Data serialization is the process of converting the state of an object into a form that can be persisted or transported. … In accessing REST service you often transfer data from client to the REST service or the other way around.

Why is serialization needed?

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.
