座位预订

Question

我正在尝试使用二维数组进行座位预订。我遇到了一个问题，输出似乎不正确，我不知道如何处理它。我已经尝试了很多次，但仍然没有做对。我只想将星号放在 2d table 或行和列内。星号代表座位。

public class BusSeatReservation {
    public static void main(String args[]) {
        System.out.println("\t\t\t\tBUS SEAT RESERVATION");
        char [][] matrix = new char [11][10];

        for (int col = 1; col <= 4; col++) {
            System.out.print("\t\tCol " + (col) + "\t");

        }
        System.out.println();
        for (int row = 1; row <= 10; row++) {
            System.out.println("Row " + (row) + "\t|");

            for (int seat = 1; seat <= 4; seat++) {
                matrix [row] [seat] = '*';
                System.out.print(matrix [row] [seat] + "\t\t");

            }

        }
        System.out.println();
    }
}

问题是您在循环内的错误位置打印制表符和换行符，但代码的主要问题是数组索引和矩阵大小。您可以通过对行数和列数使用变量来轻松解决这个问题。

public class BusSeatReservation {
    public static void main(String[] args) {
        System.out.println("\t\t\tBUS SEAT RESERVATION");
        int rows = 10;
        int cols = 4;

        char[][] matrix = new char[rows][cols];

        System.out.print("\t\t");
        for (int col = 0; col < cols; col++) {
            System.out.print("\tCol " + (col+1));

        }
        System.out.println();
        for (int row = 0; row < rows; row++) {
            System.out.print("Row " + (row+1) + "\t|\t");

            for (int seat = 0; seat < cols; seat++) {
                matrix[row][seat] = '*';
                System.out.print(matrix[row][seat] + "\t\t");

            }
            System.out.println();
        }

    }
}
