מי שמבין בjava, עשיתי לולאת for, ואני רוצה שירוץ לי על כל הi, ואז כשזה יוצא ממנה להשוות משהו ל-i לדוגמא Max=i,

אבל זה אומר cannot resolve the symbol i.
import java.util.*;
public class Targil2 {
public static Scanner reader = new Scanner(System.in);

public static void main(String[] args) {
int type;
double amount = 0, type1 = 0, type2 = 0, type3 = 0, sumtotale = 0, maxofmax = 0, maxI;
type = 4;
int i;
for (int i = 1; i <= 4; i++) {
while (type > -999) {
System.out.println("Enter your type of product");
type = reader.nextInt();
System.out.println("Enter the amount you have collected");
amount = reader.nextInt();

if (type == 1)
type1 =type1+amount * 2.5;

if (type == 2)
type2 =type2+amount * 0.5;

if (type == 3)
type3 =type3+amount * 3;
}
System.out.println("The sum of the bottles is " + type1 + " of the paper is " + type2 + " and battery is " + type3);
sumtotale = type1 + type2 + type3;
System.out.println(" the price that the class would get id " + sumtotale);
}
if (maxofmax < sumtotale)
maxofmax = sumtotale;
maxI = i;
}
}
