How Can Intersection Types Solve Lambda Serialization Problems in Java 8?

Intersecting Types for Lambda Serialization

Serializing lambdas can pose a challenge, as the exception thrown for the provided code snippet demonstrates. To address this issue, Java 8 introduces an elegant solution through the intersection of types.

By casting an object to an intersection of types via multiple bounds, it is possible to make a lambda serializable. In the context of the given code, the following code snippet can be used:

Runnable r = (Runnable & Serializable)() -> System.out.println("Serializable!");

This intersection type casting "magically" enables serialization for the lambda. This approach effectively extends the lambda with the Serializable interface without the need for an explicit SerializableRunnable "dummy" interface.
