Introduction Serialization in Java refers to the process of converting an object into a sequence of bytes, which can then be stored or transmitted over a network. This enables the object's state to be saved and later restored, allowing for easy persistence of object data. Why Serialization is Important Serialization plays a crucial role…
Introduction When designing object-oriented software in Java, developers often encounter the dilemma of choosing between composition and inheritance for code reuse and building relationships between classes.
