用Java写一个选座售票的代码

好的，我会尽力回答你的问题。以下是一个简单的用Java写的选座售票代码示例：

import java.util.Scanner;

public class SeatBookingSystem {
    private static final int NUM_ROWS = 10;
    private static final int SEATS_PER_ROW = 8;
    private boolean[][] seats;

    public SeatBookingSystem() {
        seats = new boolean[NUM_ROWS][SEATS_PER_ROW];
        for (int i = 0; i < NUM_ROWS; i++) {
            for (int j = 0; j < SEATS_PER_ROW; j++) {
                seats[i][j] = false;
            }
        }
    }

    public void printSeatingPlan() {
        System.out.println("\nSeats:\n");
        for (int i = 0; i < NUM_ROWS; i++) {
            System.out.printf("%-3d", i + 1);
            for (int j = 0; j < SEATS_PER_ROW; j++) {
                if (seats[i][j]) {
                    System.out.print("[X]");
                } else {
                    System.out.print("[ ]");
                }
            }
            System.out.println();
        }
    }

    public void bookSeat(int row, int seat) {
        if (row < 1 || row > NUM_ROWS || seat < 1 || seat > SEATS_PER_ROW) {
            System.out.println("Error: Invalid row or seat number.");
        } else if (seats[row - 1][seat - 1]) {
            System.out.println("Error: Seat is already booked.");
        } else {
            seats[row - 1][seat - 1] = true;
            System.out.println("Seat booked.");
        }
    }

    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        SeatBookingSystem system = new SeatBookingSystem();
        int row, seat;

        while (true) {
            system.printSeatingPlan();
            System.out.print("\nEnter row number (1-10) or 0 to exit: ");
            row = scanner.nextInt();
            if (row == 0) {
                break;
            }
            System.out.print("Enter seat number (1-8): ");
            seat = scanner.nextInt();
            system.bookSeat(row, seat);
            System.out.println("Press any key to continue...");
            scanner.nextLine();
            scanner.nextLine();
        }
    }
}

这个代码实现了一个简单的选座售票系统，可以打印出座位图，让用户输入座位号进行预订操作。座位状态保存在一个二维布尔数组中，true表示已经被预订，false表示还未被预订。用户输入row和seat后，调用bookSeat方法进行预订，如果座位已经被预订，则输出错误信息。预订成功后，更改座位状态为已预订，并输出成功信息。用户输入0退出程序。
