Answer
Look for concise expressions and arrow syntax.
When reading modern Java code, recognizing switch expressions by their arrow syntax (e.g., `case 'A' ->`) can quickly inform you of their intent and execution path. They are often used for returning values directly. This is common in scenarios like calculating shipping costs based on region: `int cost = switch (region) { case 'US' -> 5; case 'EU' -> 10; default -> 15; };`.
