What interface does a class need to implement to be eligible for serialization?

A. Serializable Here's why the other options are not required for serialization: B. Cloneable: This interface is used for creating a copy of an object. While it can be useful in some scenarios, it's not mandatory for serialization. C. ObjectOutputStream: This class is used to write objects to an OutputStream during serialization. It's not an interface that a class needs to implement. D. DataOutputStream: This class is used to write primitive data types to an OutputStream. It's not relevant for object serialization itself. Serializable Interface: The Serializable interface is a marker interface. It doesn't require any specific methods to be implemented. However, classes that intend to have their objects serialized must implement this interface to indicate that serialization is supported. Serialization Process: When you serialize an object, its state (field values) is converted into a byte stream format. This byte stream can then be written to a file, transmitted over a network, or stored elsewhere. Deserialization: The counterpart of serialization is deserialization. Here, the byte stream is used to recreate the original object with its state. 4/97
