Answer
They provide a way to add new methods to interfaces without breaking existing implementations.
Default methods in interfaces allow developers to add new functionality to interfaces while maintaining backward compatibility with existing classes. This is especially useful when evolving libraries or APIs. For example, an interface `Logger` might add a `default` method `logDebug()` that provides basic logging functionality without forcing all implementing classes to update.
