Can somebody tell me what is wrong with this code?
package pl.codegym.task.task07.task0708;
import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.util.ArrayList;
import java.util.List;

public class Solution {
private static List<String> strings;
public static void main(String[] args) throws Exception {
ArrayList<String> lista = new ArrayList<String>();
ArrayList<String> max = new ArrayList<String>();
BufferedReader reader = new BufferedReader (new InputStreamReader(System.in));
String s = "";
// String string = "";
for (int i = 0; i < 5; i++){
String string = reader.readLine();
lista.add(string);
if(lista.get(i).length() > s.length()){
s = lista.get(i);
}
}
for (int i = 0; i < lista.size();i++){
if (s.length() == lista.get(i).length()){
max.add(lista.get(i));
}
}
for(int i = 0; i < max.size();i++){
System.out.println (max.get(i));
}
}
}
