1Z0-829 Controlling Program Flow Practice Question

Which three of the following are valid case values in a traditional switch statement (non-pattern)?

⚠ Common exam trap

Many exam-takers assume any primitive type or literal can be used in a switch case, forgetting that only byte, short, char, int, String, and enum constants are allowed, and that boolean and floating-point types are explicitly excluded.

Correct answer & explanation

✓

In a traditional switch statement (non-pattern), the case values must be compile-time constants of types that are compatible with the switch expression. Integer literals like 42 are valid case values, as they are constant expressions of type int, which is one of the allowed types (byte, short, char, int, their wrapper classes, String, and enum types).
