Answer
A compilation error occurs. Frame the concept in practical terms so you can explain it during interview discussion.
If a switch expression in Java 17 checks an enum and does not include cases for all possible values or a default case, the code will not compile. This feature ensures that developers handle all possible scenarios, reducing the risk of unhandled cases leading to runtime errors.
