On line 17, the compiler says it can't find the ArrayList symbol. I don't understand why.
package com.codegym.task.task07.task0719;
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
/*

public class Solution {
public static void main(String[] args) throws IOException {
BufferedReader reader = new BufferedReader(new InputStreamReader(System.in));
//write your code here
ArrayList<Integer> list = new ArrayList<>();
for (int i = 0; i < 10; i++)
{
int s = Integer.parseInt(reader.readLine());
list.add(s);
}
for (int i = 0; i < list.size(); i++)
{
int j = list.size() - i - 1;
System.out.println( list.get(j) );
}
}
}
