I use ArrayList and loop for each element from this list so how can i go out of bounds?
package pl.codegym.task.task09.task0921;
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.util.ArrayList;
/*
Metoda w try-catch
*/
public class Solution {
public static void main(String[] args) {
czytajDane();
}
public static void czytajDane() {
BufferedReader reader = new BufferedReader(new InputStreamReader(System.in));
ArrayList<Integer> list = new ArrayList<>();
while (true) {
try {
list.add(Integer.parseInt(reader.readLine()));
} catch (NumberFormatException e) {
for (Integer i : list) System.out.println(list.get(i));
} catch (IOException e) {
}
}
}
}
