Hi, I am trying to run a code below
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
for (i=1; i<=3; i++){
amount = amount * 0.9 ;
}
System.out.println("Your debt is " + amount );
}
}
But it gave a mistake
Line 0
Cannot resolve symbol
And that is code from exercise and have been written by content developer, not me.
and it is started somehow from line 1 (my guess line 0 is hidden from pupils)
Can somebody tell me what I am doing wrong? Thanks in advance

You didn't declare i
You cannot assign double value to int
and don't print anything except only value.
for (int i=1; i<=3; i++){
amount = amount * 90 / 100 ;
}
System.out.println( amount );
Yes ,code works fine now, but now I don't understand why it doesn't take something like
(double) amount = (double) amount * 0.9;
🤔
And question about debagger, why it pointed for me to "line 0", not like "line 9"?

You declared amount as int so (double) amount would be wrong. You need to assign it to another variable with double data type
double abc = (double) amount;
abc = (double) amount * 0.9;
So basically you need to take input as double if you want to solve like that.
About error that's the problem of Sololearn terminal. I think they put as alert so we get message like that.
