    Default int's not adding together for some unknown reason

    I for the life of my cannot figure out why this code isnt working.
    I want the integer trueLength to be the collective values of all the integers in the int array totals. For some reason I keep getting zero as the total even though totals contains numbers greater than zero.

    Please help.

    public int[] FrequencyFinder(File textfile) throws IOException
    Scanner infile = new Scanner(textfile);
    int trueLength = 0;
    file += infile.nextLine();
    String[] alphabet = {"a","b","c","d","e","f","g","h","i","j","k","l"," m","n","o","p","q","r","s","t","u","v","w","x","y" ,"z"};
    int[] totals = {0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0 ,0, trueLength};

    for(int cc = 0; cc < file.length(); cc++)
    for(int aa = 0; aa < alphabet.length; aa++)
    if(file.substring(cc,cc + 1).equalsIgnoreCase(alphabet[aa]))
    totals[aa] ++;


    for(int x = 0; x < totals.length; x++)
    trueLength += totals[x];
    return totals;

    Default Re: int's not adding together for some unknown reason

    Looks like the totals array was initialized with the starting value of trueLength, which was zero. Also it looks like the variable trueLength was calculated to be the total of the values in the totals array from 0 to 25 but totals[26] was not then updated with the final value of trueLength.

    So the question is was the final value of trueLength used to update the totals array?
