Answer
Switch expressions provide a more concise and flexible syntax.
Switch expressions, available from Java 12, allow for returning values directly and supporting multiple labels, thereby reducing boilerplate code and potential errors. For instance, calculating discounts based on user type in an e-commerce application becomes simpler: `int discount = switch (userType) { case 'VIP' -> 20; case 'Regular' -> 10; default -> 0; };`. This reduces the risk of fall-through errors and enhances clarity.
