문제의 코드

package test;

class MyMovie {
    private String title; // 영화제목
    private String[] seats; // 좌석

    public MyMovie(String title, int seatCount) {
        this.title = title;
        this.seats = new String[seatCount];

        for (int i = 0; i < seatCount; i++) {
            seats[i] = "A" + (i + 1);
        }
    }

    public String[] getSeats() {
        return seats;
    }
}


public class MyMovieReservationSystem {
    public static void main(String[] args) {
        MyMovie Movie = new MyMovie("헤리포터", 7);
        System.out.println(Movie.getSeats(0));
    }
}

해결

package test;

class MyMovie {
    private String title; // 영화제목
    private String[] seats; // 좌석

    public MyMovie(String title, int seatCount) {
        this.title = title;
        this.seats = new String[seatCount];

        for (int i = 0; i < seatCount; i++) {
            seats[i] = "A" + (i + 1);
        }
    }

    public void getSeats() {
        for (int i = 0; i < seats.length; i++) {
            System.out.print("[" + seats[i] + "]");
        }
    }
}


public class MyMovieReservationSystem {
    public static void main(String[] args) {
        MyMovie Movie = new MyMovie("헤리포터", 7);
        Movie.getSeats();
