Question

Write a complete Java program with methods that prompt user for the number of floors, rooms, occupied rooms in a hotel. You must validate floors, rooms, occupied rooms. Compute vacant rooms, occupancy rate on each floor and display rooms, occupied rooms, vacant rooms and occupancy rate for each floor. Use the given method names. See validation rules below:

1. getFloors(). This method prompts user for number of floors in a hotel and returns floors to the caller.

2. testFloors(floors). Do not accept a value less than 1 for the number of floors. A loop should then iterate once for each floor. During each iteration, the loop prompts user for

3. getRooms(). Method prompts user for number of rooms on the floor and returns rooms.

4. testRooms(rooms) Do not accept a value less than 10.

5. getOccRooms(). Method prompts user for number of rooms that are occupied and returns occupied rooms.

6. testOccRooms(occRooms, rooms). Do not accept a value greater than the number of rooms on the floor.

7. computeVacRooms(rooms, occRooms) Calculate the number of vacant rooms on each floor and return vacant rooms.

8. computeOccRate(occRooms, rooms) Calculate the occupancy rate on each floor and return occupany rate. Occupancy rate = 100 * (double)rooms occupied / rooms on floor

9. display(rooms, occRooms, vacRooms, occRate) on each floor You may calculate totalRooms, totalOccRooms and totalVacRooms in the hotel inside the loop.

10. computeHotelOccRate(totalOccRooms, totalRooms)Calculate the occupancy rate for the hotel outside the loop. Hotel Occupancy Rate = 100 * (double)totalOccupiedRooms / totalRooms

11. display(totalRooms, totalOccRooms, totalVacRooms, hotelOccRate) for the hotel.

Output:

1. Rooms on each floor

2. Occupied rooms on each floor

3. Vacant rooms on each floor

4. Occupancy rate for each floor

5. Total number of rooms the hotel has

6. Total number of occupied rooms the hotel has

7. Total number of vacant rooms the hotel has

8. Occupancy rate for the hotel Note: 1-4 inside the loop; 5-8 outside the loop

Submit this printout and the following:

1. An algorithm

2. A complete Java Program (include comments/documentation in your program)

3. Output (see above)

Test Data Floors Rooms Occupied 1 10 8 2 15 12 3 20 25

Note: Invalid Occupied Rooms on floor 3.

Use valid number 18 to complete your program.

Using this as a guide line how would one make this program's layout ?

Essentially I have this :

import java.util.Scanner;

import java.text.DecimalFormat;

public class HotelFloors

{

public static void main(String[] args) {

int numFloor;

Scanner s = new Scanner(System.in);

DecimalFormat df = new DecimalFormat("#.##");

System.out.print("\nEnter number of floors, at least 1: ");

do{

numFloor = s.nextInt();

if(numFloor<1)

{

System.out.print("\nSorry there should be at least 1 floor, enter the number again: ");

}

}while(numFloor<1);

int totalRooms = 0;

int totalOccRoom = 0;

for(int i=1;i<=numFloor;i++)

{

int nRoom,occRoom;

if(i==13)

continue;

  

System.out.print("\nFloor "+i+" ");

System.out.print("\nPlease enter the number of rooms on the floor, at least 10: ");

do

{

nRoom = s.nextInt();

if(nRoom<10)

{

System.out.print("\nSorry there should be at least 10 rooms, enter the number again: ");

}

}while(nRoom<10);

  

totalRooms = totalRooms + nRoom;

  

System.out.print("\nPlease enter the number of rooms that are occupied on that floor: ");

do{

occRoom = s.nextInt();

if(occRoom>nRoom)

{

System.out.print("\nSorry occupancy number cannot be greater than total room, enter again: ");

}

}while(occRoom>nRoom);

  

double roomOccupancy = (double)occRoom/(double)nRoom;

  

totalOccRoom = totalOccRoom + occRoom;

  

System.out.print("\nFloor " + i +": " + nRoom +" rooms, "+ occRoom +" occupied. The occupancy rate for floor "+ i+ " is "+ df.format(roomOccupancy) +"\n");

}

double totalOccupancy = (double)totalOccRoom/(double)totalRooms;

System.out.print("\n\n****************************************");

System.out.print("\nAltogether,the hotel has " + totalRooms + " rooms,"+ totalOccRoom + " rooms are occupied, " + (totalRooms - totalOccRoom) +"rooms are vacant. The overall occupancy rate for the hotel is " + df.format(totalOccupancy));

}

}

How do I put this in a method format
