My program works ok and I do initialize the list of Strings.
package com.codegym.task.task07.task0709;
import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.util.ArrayList;
import java.util.List;
import java.util.Scanner;
/*
Expressing ourselves more concisely
*/
public class Solution {
public static void main(String[] args) throws Exception {
List<String> strings = new ArrayList<String>();
List<String> minList = new ArrayList<String>();
Scanner sc = new Scanner(System.in);
for (int i = 0; i < 5; i++) {
strings.add(sc.nextLine());
}
String minL = strings.get(0);
for (String s : strings ) {
if(minL.length() > s.length()) minL = s;
}
for (String s : strings) {
if(minL.length() == s.length()) minList.add(s);
}
for (String s : minList) {
System.out.println(s);
}
}
}
