Write a Java program to compute the amount of the debt in n months

import java.util.Scanner;
public class Main { 
    public static void main(String[] args) {
   Scanner s = new Scanner(System.in);
   System.out.println("Input number of months:");
        int n = s.nextInt();
        double c = 100000;
        for(int i = 0; i < n; i++) {
            c += c*0.04;
            if(c % 1000 != 0) {
                c -= c % 1000;
                c += 1000;
            }             
        }
       System.out.println("\nAmount of debt: ");
        System.out.printf("%.0f\n",c);
    }
}

Sample Output:

Input number of months:
 6

Amount of debt: 
129000
