Serializable
Serializable is a programming concept that refers to the ability of an object or data structure to be converted into a format (such as a byte stream, JSON, or XML) that can be easily stored, transmitted, or reconstructed later. This process, called serialization, allows data to persist across sessions, be sent over networks, or shared between different systems or programming languages. Deserialization is the reverse process of reconstructing the original object from the serialized format.
Developers should learn and use serialization when they need to save application state, cache data, send objects over a network (e.g., in APIs or distributed systems), or integrate with external services that require data in a standardized format. It is essential for tasks like saving user preferences, transmitting data in web applications, or working with databases and message queues, as it enables efficient data handling and interoperability.
