A Metropolitan Hotel has 5 floors and 10 rooms in each floor. The names of the visitors are entered in a Double Dimensional Array (DDA) as M[5][10].The Hotel Manager wants to know from the "Enquiry" about the position of a visitor (i.e. floor number and room number) as soon as he enters the name of the visitor. Write a program in Java to perform the above task.

import java.util.Scanner;

public class KboatHotelEnquiry
{
    public static void main(String args[]) {
        Scanner in = new Scanner(System.in);
        String M[][] = new String[5][10];
        int i = 0, j = 0;
        
        for (i = 0; i < 5; i++) {
            System.out.println("Enter floor " + (i + 1) 
                + " guest details:");
            for (j = 0; j < 10; j++) {
                System.out.print("Guest in room " + 
                    (j + 1) + ": ");
                M[i][j] = in.nextLine();
            }
        }
        
        boolean found = false;
        System.out.print("\nEnter guest name to search: ");
        String guest = in.nextLine();
        for (i = 0; i < 5; i++) {
            for (j = 0; j < 10; j++) {
                if (M[i][j].equals(guest)) {
                    found = true;
                    break;
                }   
            }
            
            if (found)
                break;
        }
        
        if (found)
            System.out.println(guest + " is in room number "
                + (j + 1) + " on floor number " + (i + 1));
        else
            System.out.println(guest + 
                " is not staying at this hotel");
    }
