What is wrong in this code?

Question

Q.....
You take a loan from a friend and need to calculate how much you will owe him after 3 months.
You are going to pay him back 10% of the remaining loan amount each month.
Create a program that takes the loan amount as input, calculates and outputs the remaining amount after 3 months.

Sample Input:
20000

Sample Output:
10628

Here is the monthly payment schedule:
Month 1
Payment: 10% of 20000 = 2000
Remaining amount: 18000
Month 2
Payment: 10% of 18000 = 1800
Remaining amount: 16200
Month 3:
Payment: 10% of 16200 = 1620
Remaining amount: 14580

My code.....
import java.util.Scanner;

public class Program
{
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
int amount = scanner.nextInt();
//your code goes here
amount = 20000;
int Payment = (20000 * 10)/100;
do{
System.out.println("pay:"Payment);
amount = amount - payment;
} while(amount >= 0);
}
}

Answer 1

First, u need to include the payment in the do-while loop because u need to calculate the payment every month.
Next, output your result after calculation.
Lastly, The condition should be cater for the months instead of the amount.

Solution:

import java.util.Scanner;

public class Program
{
public static void main(String[] args) {

int month = 3;
Scanner scanner = new Scanner(System.in);
int amount = scanner.nextInt();
//your code goes here

int payment;
do{
payment = (amount * 10)/100;
amount = amount - payment;
System.out.println("pay:" + amount);

month--;
} while(month > 0);
}
}

Of course, the remaining part I'll leave it for u to work out
