Loan Calculator quiz am i missing something

Question

The loan calculator quiz asks for an output of total amount left to pay after paying 10% back once a month for 6 months.

int amount = scanner.nextInt();
int payment=0;
int months=0;
while(months <6)
{
payment = amount/10;
amount = amount -payment;
months++;
}
This was my answer and it said i was one dollar off. How do i correct the rounding?

Answer 1

import java.util.Scanner;

public class Program
{
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
double amount = scanner.nextInt();
//your code goes here
int i=0;
do{
amount=amount-(Math.ceil(amount/10));
i++;
}
while(i<6);
System.out.println((int)amount);
}
}
You need to use math.ceil method also use do while loop.
