Hello,
Is that bug, or I did something wrong?
package pl.codegym.task.task10.task1017;
import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.util.ArrayList;
/*
Bezpieczne odzyskiwanie z listy
*/
public class Solution {
public static void main(String[] args) throws Exception {
BufferedReader reader = new BufferedReader(new InputStreamReader(System.in));
ArrayList<Integer> lista = new ArrayList<Integer>();
for (int i = 0; i < 20; i++) {
int x = Integer.parseInt(reader.readLine());
lista.add(x);
}
System.out.println(bezpiecznieGetElement(lista, 5, 1));
System.out.println(bezpiecznieGetElement(lista, 20, 7));
System.out.println(bezpiecznieGetElement(lista, -5, 9));
}
public static int bezpiecznieGetElement(ArrayList<Integer> lista, int indeks, int wartoscDomyslna) {
int zwrot;
try {
zwrot = lista.get(indeks);
} catch(IndexOutOfBoundsException e) {
zwrot = lista.get(wartoscDomyslna);
}
return zwrot;
}
}
