문제 풀이

• LocalTime 클래스의 minusMinutes 메서드를 사용하여 시간 뺄셈

public class Main {
    public static void main(String[] args) throws IOException {
        BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
        StringTokenizer st = new StringTokenizer(br.readLine());
        int hour = Integer.parseInt(st.nextToken());
        int minute = Integer.parseInt(st.nextToken());

        LocalTime localTime = LocalTime.of(hour, minute).minusMinutes(45);
        System.out.println(localTime.getHour() + " " + localTime.getMinute());
    }
}
