Answer 1

import java.util.Scanner;

public class Main {
    public static void main(String[] args) {
        Scanner in = new Scanner(System.in);
        int[][] seats = new int[10][4];
        System.out.println("Bus Seat Reservation:");
        while (true) {
            System.out.println("Col 1 Col 2 Col 3 Col 4");
            for (int i = 0; i < seats.length; i++) {
                System.out.print("row " + (i + 1) + " | ");
                for (int j = 0; j < seats[i].length; j++) {
                    System.out.print(seats[i][j] == 0 ? "* " : "X ");
                }
                System.out.println();
            }
            System.out.print("Enter row and column no. to reserve separated by space (enter negative no. to exit): ");
            int row = in.nextInt();
            int column = in.nextInt();
            if (row < 0 || column < 0) {
                break;
            }
            seats[row - 1][column - 1]++;
        }
