java - Importing and Splitting CSV input, Need helping reading only first character of -

working on class project, having trouble data after read array.

in excel spreadsheet, need read straight down column paying attention first digit in each block. when split column continuous string no space can't figure out how count first digit opposed counting each digit (as code now). example: (11, 20, 296) split, becoming "1120296"

        final int[] benfordlaw = {0, 30, 18, 13, 10, 8, 7, 6, 5, 5};         int[] actualprecent = new int[10];         int benfordscore = 0;         float[] countfornum = new float[10];         float totalcount = 0;          //this while loop read through each line of file         while (scan.hasnextline()) {              // statement reads in next line of file.             string line = scan.nextline();              string[] values = line.split(",(?=(?:(?:[^\"]*+\"){2})*+[^\"]*+$)");               //12-15 column #'s             (int = 12; < 15; ++i) {                 (int j = 0; j < values[i].length(); j++) {                     char chara = values[i].charat(j);                     (int k = 1; k <= 9; ++k){                         char compare = (char)(k + '0');                         if (chara == compare) {                             ++countfornum[k];                             ++totalcount;                         }                     }                 }             }         } 

i think didn't totally question, hope helps

example: (11, 20, 296) split, becoming "1120296" => if want 11 in text

read line , string sol 1. ) a) remove first , last char b) split.text , trim it. c) first one

sol 2. ) use regex , first element ex regex.) ([0-9]*),

good luck
