What does the Serializable interface contain?
- A set of methods for creating new objects
- A set of methods for mathematical calculations
- A set of methods for serializing objects

The Serializable interface in Java does not contain any methods. Instead, it serves as a marker interface, indicating that the class implementing it can be serialized. Serialization allows objects to be converted into a byte stream for storage or transmission. It's used for objects that need to be saved to a file or sent over a network.
