Валидатор утверждает, что вот этот код:
for ( ; countFrom-- > 0 ; ) {
Thread.sleep(500);
System.out.println(list.get(countFrom));package com.javarush.task.task16.task1614;

list.add("Строка " + i);
}
}
public static void main(String[] args) throws InterruptedException {

t.start();
}
public static class Countdown implements Runnable {

}
} catch (InterruptedException e) {

public void printCountdown() throws InterruptedException {
//add your code here - добавь код тут
