Works - but not passing read 5 strings

Question about the task

Archived

Not sure the issue, i have confirmed 5 strings are being read commented section, but i still don't pass the requirement - everything else passes

1. Initialize the list of strings.
2. Read 5 strings from the keyboard and add them to this list.
3. Using a loop, find the longest string in the list.
4. Display the string. If there is more than one, display each on a new line.

Requirements:

In the main method, initialize the Solution class's existing strings field to a new ArrayList<>.
The program should read 5 strings from the keyboard and write them to the list of strings.
The program should display the longest string.
If several strings qualify as the longest, then you need to display each of them on a new line.

package com.codegym.task.task07.task0708; import java.io.BufferedReader; import java.io.InputStreamReader; import java.util.ArrayList; import java.util.List; /* Longest string */ public class Solution { private static ArrayList<String> strings = new ArrayList<String>(); public static void main(String[] args) throws Exception { //write your code here BufferedReader reader = new BufferedReader(new InputStreamReader(System.in)); ArrayList<String> strings = new ArrayList<String>(); ArrayList<String> longest = new ArrayList<String>(); String words; for(int i = 0; i <= 4; i++) { words = reader.readLine(); strings.add(words); } /* for(int i = 0; i <= 4; i++) { System.out.println(strings.get(i)); } */ int longst = strings.get(0).length(); for(int i = 0; i <= (strings.size()-1); i++) { int current = strings.get(i).length(); if (longst <= current) { longst = current; } } for(int i = 0; i <= (strings.size()-1); i++) { if(strings.get(i).length() == longst) { longest.add(strings.get(i)); } } for(int i = 0; i <= (longest.size()-1); i++) { System.out.println(longest.get(i)); } } }

You declared strings twice, so you just gotta delete line 19 ;) ArrayList<String> strings = new ArrayList<String>();

Hello! I ran over the part where you are adding strings into the array (line 23). Even though your function for(int i = 0; i <= 4; i++) reads 5 strings, I think the <= confuses the verification program. Try simply for(int i = 0; i < 5; i++) and see if it passes. It is just my guess. Let me know if it passes, I am very interested!
