Exception handling in Spring Boot

Rewrite using a basic class

Report a typo

Here is the class for the exception:

Take a look at the following method that processes requests:

Java

@GetMapping("flights/{id}")
public FlightInfo getFlightInfo(@PathVariable int id) {
    for (FlightInfo flightInfo : flightInfoList) {
        if (flightInfo.getId() == id) {
            return flightInfo;
        }
    }

    throw new FlightNotFoundException("Flight not found for id =" + id);
}

Kotlin

@GetMapping("flights/{id}")
fun getFlightInfo(@PathVariable id: Int): FlightInfo {
    if (id > flightInfoList.size) {
        throw FlightNotFoundException("Flight not found for id =$id")
    }
    return flightInfoList[id]
}

How can you rewrite the code above without using the custom exception FlightNotFoundException?

Java

@ResponseStatus(code = HttpStatus.BAD_REQUEST)
class FlightNotFoundException extends RuntimeException {
    // ...
}

Kotlin

@ResponseStatus(code = HttpStatus.BAD_REQUEST)
class FlightNotFoundException : RuntimeException() { 
    // ...
}

Select one option from the list

Throw new ResponseStatusException()

Throw new ResponseStatusException(HttpStatus.BAD_REQUEST)

It's impossible

Throw new ResponseStatusException(HttpStatus.BAD_REQUEST, "Flight not found for id =" + id)
