Question

Using Loops for the Hotel Occupancy calculator.

You will write a program that calculates the occupancy of a hotel. Rules: 1# The hotel must have more than 2 floors and less than or equal 5 floors. 2# Each floor in the hotel can have a different number of rooms on the floor. 3# You must set the number of occupied rooms. Again, there must less rooms occupied than the number of rooms. 4# Using the total number of rooms and the total number of occupied rooms calculate the occupancy rate of the hotel. 5# Every input into this program must be checked to see if the numbers are valid.

JAVA

Answer 1

import java.util.Scanner;

public class HotelOccupancyCalc {
   public static void main(String[] args) {
       Scanner sc = new Scanner(System.in);
       int floors;
       int totalRooms = 0;
       int totalOccupied = 0;
       double percentage;
       //reading floors
       while (true) {
           System.out.println("Enter number of floors: ");
           floors = sc.nextInt();
           //if it is valid floor break loop
           if (floors >= 2 && floors <= 5)
               break;
           // if it is invalid..keep asking for valid value
           System.out.println("Invalid input. try again..");
       }
       //reading total rooms and occupied rooms for each floor
       for (int i = 0; i < floors; i++) {
           System.out.println("Enter total rooms at floor " + (i + 1));
           totalRooms += sc.nextInt();
           System.out.println("Enter total occupied rooms at floor " + (i + 1));
           totalOccupied += sc.nextInt();
       }
       //finding percentage
       percentage = totalOccupied / (double) totalRooms;
       percentage = percentage * 100;
       System.out.println("Total rooms: "+totalRooms);
       System.out.println("Total occupied rooms: "+totalRooms);
       System.out.println("Hotel occupany : " + percentage + "%");
   }
}
