Question

Here is the code:

class Test {
    public static void main (String[] args) throws Exception {
        java.io.File fail = new java.io.File("C:/Users/Student/Desktop/Morze.txt");
        java.util.Scanner sc = new java.util.Scanner(fail);
        while (sc.hasNextLine()) {
             String line = sc.nextLine();
             String[] lst = line.split(" ");
             int[] letter = new int[26];
             int[] sumbol = new int[26];
             for (int i = 0; i < lst.length; i++)
                 System.out.print(lst[i] + " ");
             System.out.println();
                     // How to add?
        }
    }
}

Please, explain how can I add all letters into list Letter and symbols into list Sumbol?

You don’t have a list, you have an array(s). It appears you want to add the values to two arrays. However you appear to have some code in your loop which should not be in your loop.

Additionally your data is text/String not numbers/int values.

String[] letter = new String[26];
String[] symbol = new String[26];
int count = 0;
while (sc.hasNextLine()) {
    String line = sc.nextLine();
    String[] lst = line.split(" ");
    letter[count] = lst[0];
    symbol[count] = lst[1];
    count++;
}
for (int i = 0; i < count; i++)
    System.out.println(letter[i] + " " + symbol[i]);
