What is wrong here? Can not proceed further [JAVA]

Question

Hello, colleagues! I completed Loam Calculator JAVA Challenge, but I can't proceed, as Code Analyzer showing message that I got a bug there. However 2 Test Cases passed, and output completely identical. There are 3 test cases that are hidden, may be something wrong there? Below is 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
int term = 3;
for (int i = 1; i <= term; i++ ) {
int payment = amount / 100 * 10;
amount = amount - payment;
}
System.out.println(amount);
}
}

Please help, I'm stuck :((

Answer 1

Try to use a double value in calculations.
Try this.
amount -=(amount/100.0 *10)
In loop..

its equivalent to
for (int i = 1; i <= term; i++ ) {
double payment = amount / 100.0 * 10;
amount = (int)(amount - payment);
}

Answer 2

Thank you for the answer. But in task description asked to use Integers for amounts

You can use integer also but you need to change your calculation logic like:

for(int a = 1; a<=term; a++){
amount = amount - amount * 10 / 100;
}

System.out.println(amount)

You are first dividing amount by 100 so issue is there.

To understand problem see below problem:

System.out.println (90 / 100 * 10); //0
System.out.println (90 * 10 / 100); //9

both will give different result

Answer 4

Yes. Amount is of integer but in calculations for interest, if you use a double value then it won't miss praction part. Later you can convert back to int and display as I given above. Not changed the amount type but used a double type in calculations..
Check it once and reply if wrong..
Hope it helps...
