Have you converted reference data types to primitive types in Java?

Yes, there is experience working with unboxing in Java. Unboxing is the process of converting an object of a wrapper class (like Integer) to its corresponding primitive type (like int). It happens automatically in Java when needed.

For example:

Integer integerObject = 10; // auto-boxing
int primitiveInt = integerObject; // unboxing

This is useful when working with primitives for performance reasons or when using APIs that require primitive types.
