Question

This Intellij JAVA

A heating utility company allows customers to spread the cost of bills through the year by charging them an average payment every month.

The utility company averages all of the last year's bills, and uses that to estimate the average payment for next year.

Ask the user for each month's bill for last year.

Store this data in an array.

Store January's bill in element 0, February's in element 1…

Then, add up all of the bills and figure out the average; the average of all of the bills in one year will become next year’s monthly payment.

Also, display the user's data in a table of months and bill amount, so they can review it for accuracy.

Tip: use another array with the names of the months to help ask for data/display data. You can copy/paste this:

String[] months = { "January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December" };

Explanation / Answer

package snippet;

import java.util.Scanner;

public class Bill {

   public static void main(String[] args) {
       // TODO Auto-generated method stub
      
       String[] months = { "January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December" };
       int[] bill=new int[12];//Array to hold bill of each month
       Scanner sc=new Scanner(System.in);//create scanner object
      
       int sum=0;
       float avg=0;
      
       for(int i=0;i<12;i++)
       {
           System.out.println("Enter payment for month "+months[i]);
           bill[i]=sc.nextInt();//accept payment
           sum+=bill[i];//add it to sum
       }
      
       //display table
       System.out.println("Month Payment");
       for(int i=0;i<12;i++)
       {
           System.out.println(months[i]+" "+bill[i]);
          
       }
       //calculate average
       avg=sum/12;
       System.out.println("Total Payment "+sum);
       System.out.println("Average Payment "+avg);
      

   }

}
