    Default Count Number of Each Letter in Given Word?

    Hi, So I'm trying to write a program in which the user enters a word, then the program displays each letter of the alphabet and how many times each letter is used in that word.
    Ex. "Testing" A-0 B-0 .... S-1 T-2
    Like that

    However, I don't know whats wrong with the code and how to fix it?
    Any help is appreciated

    import java.lang.String;
     
    public class Words
    {
    public static void main(String[]args)
    {
    String words = new String();
    words = Input.getString("Please enter a statement");
     
    int[]total = totalLetters(words.toLowerCase());
     
    for (int i=0; i < total.length; i++)
    {
    if (total[i]!=0) 
    System.out.println("Letter " + (char)('a' + i) + " count = " + total[i]);
    }
    }
     
    public static int[]totalLetters(String words)
    {
    int[]total = new int[26];
     
    for (int i=0; i < words.length(); i++) 
    {
    if (Character.isLetter(words.charAt(i))) 
    {
    total[words.charAt(i) - 'a']++ ;
    }
    }
     
    return total;
     
    }
    }

    What makes you think there's something wrong with your code?
