Question about the task

Archived

My code works when I test it, but codegym tests failes. Why?

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; import java.util.Scanner; /* Longest string */ public class Solution { private static List<String> strings = new ArrayList<>(); public static void main(String[] args) throws Exception { Scanner sc = new Scanner(System.in); for (int i = 0; i < 5; i++) { String s = sc.nextLine(); strings.add(s); } String max = ""; for (int i = 0; i < strings.size(); i++) { if (strings.get(i).length() > max.length()) { max = strings.get(i); } } for (int i = 0; i < strings.size(); i++) { if (max.length() == strings.get(i).length()) { System.out.println(strings.get(i)); } } sc.close(); } }

try this:

private static List<String> strings;

public static void main(String[] args) throws Exception {
   strings = new ArrayList<>();
   Scanner sc = new Scanner(System.in);
   // rest of code
}

I'm thinking this is your problem because the starting code for this task is:

public class Solution {
    private static List<String> strings;

    public static void main(String[] args) throws Exception {
        //write your code here
    }
}

and you coded where it doesn't say to add code. I'm not sure this is the problem but give it a try.
