Question

My homework is write a prgram for hotel occupancy rate. I figured out everything expect occupacy rate of the floor. How to calculate occupancy rate of each floor?

import java.util.Scanner;

public class Hwk6 {

public static void main(String[] args) {

int floors = 0;

int rooms = 0;

int roomsTotals = 0;

double roomsOccupied = 0;

double roomsOccupiedTotals = 0;

double occupancyRate = 0;

Scanner stdin = new Scanner(System.in);

System.out.println(" Hotel room occupacy rate calculator ");

System.out.print("Enter the number of floors: ");

floors = stdin.nextInt();

while(floors < 1) {

System.out.print("The number of floors must greater than 0. ");

floors = stdin.nextInt();

}

for(int i=0; i<floors; i++){

System.out.print("Enter the number of rooms [Floor " + (int)(i + 1) + "]: ");

rooms = stdin.nextInt();

while(rooms < 8){

System.out.print("The minimum number of rooms are 8. [Floor " + (int)(i + 1) + "]: ");

rooms = stdin.nextInt();

}

System.out.print("Enter the number of rooms occupied [Floor " + (int)(i + 1) + "]: ");

roomsOccupied = stdin.nextInt();

roomsOccupiedTotals += roomsOccupied;

roomsTotals += rooms;

occupancyRate = (roomsOccupiedTotals/roomsTotals);

}

System.out.println("Total Rooms: " + roomsTotals);

System.out.println("Occupacy rate for entire hotel: " + occupancyRate);

}

}

Explanation / Answer

Added comments for added code:

Hwk6.java

import java.text.DecimalFormat;

import java.util.Scanner;

public class Hwk6 {

public static void main(String[] args) {

int floors = 0;

int rooms = 0;

int roomsTotals = 0;

double roomsOccupied = 0;

double roomsOccupiedTotals = 0;

double occupancyRate = 0;

//To round off up to two decimals for the occupancy rate

DecimalFormat format1 = new DecimalFormat("0.00");

Scanner stdin = new Scanner(System.in);

System.out.println(" Hotel room occupacy rate calculator ");

System.out.print("Enter the number of floors: ");

floors = stdin.nextInt();

while (floors < 1) {

System.out.print("The number of floors must greater than 0. ");

floors = stdin.nextInt();

}

//create array to store each floor occupancy

double[] floorOccupancy=new double[floors];

for (int i = 0; i < floors; i++) {

System.out.print("Enter the number of rooms [Floor " + (int) (i + 1) + "]: ");

rooms = stdin.nextInt();

while (rooms < 8) {

System.out.print("The minimum number of rooms are 8. [Floor " + (int) (i + 1) + "]: ");

rooms = stdin.nextInt();

}

System.out.print("Enter the number of rooms occupied [Floor " + (int) (i + 1) + "]: ");

roomsOccupied = stdin.nextInt();

//store floor occupancy of each floor

floorOccupancy[i]=roomsOccupied/rooms;

roomsOccupiedTotals += roomsOccupied;

roomsTotals += rooms;

occupancyRate = (roomsOccupiedTotals / roomsTotals);

}

System.out.println("Total Rooms: " + roomsTotals);

System.out.println("Occupacy rate for entire hotel: " + format1.format(occupancyRate));

//Print occupancy rate for each floor with formatted values

for (int i = 0; i < floorOccupancy.length; i++) {

System.out.println("Floor Occupancy of [Floor "+(int)(i+1)+"]: "+format1.format(floorOccupancy[i]));

}

//close the scanner

stdin.close();

}

}

Sample output:

Hotel room occupacy rate calculator

Enter the number of floors: 2
Enter the number of rooms [Floor 1]: 10
Enter the number of rooms occupied [Floor 1]: 3
Enter the number of rooms [Floor 2]: 6
The minimum number of rooms are 8.
[Floor 2]: 10
Enter the number of rooms occupied [Floor 2]: 4
Total Rooms: 20
Occupacy rate for entire hotel: 0.35
Floor Occupancy of [Floor 1]: 0.30
Floor Occupancy of [Floor 2]: 0.40
