我正在尝试使用二维阵列进行座位预订。我遇到了一个问题，其中输出似乎不正确，我不知道如何处理它。我已经尝试了很多次，但仍然没有正确。我只想将星号放在二维表内或行和列内。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();
}
}

问题是您在回圈中的错误位置打印制表符和新行，但您的代码的主要问题是阵列索引和矩阵大小。您可以通过使用变量来表示行数和列数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();
        }

    }
}
