(Java) How can I count the number of tab and space before the first character of a string

Assume that a string String line = " Java is good."

There are totally 10 spaces in this string. However, how can I count the number of tab and space before the first character "J" only? There are 8 spaces before the first character "J" only.

Solution

How about:

    String s = "        Java is good.";
    int total = 0;
    for (int i = 0; i < s.length(); i++) {
      if (Character.isWhitespace(s.charAt(i))) {
        total++;
      } else {
        break;
      }
    }
    System.out.println(total);

Or

    String s = "        Java is good.";
    int total = 0;
    for (int i = 0; i < s.length(); i++) {
      char ch = s.charAt(i);
      if (ch == ' ' || ch == '\t') {
        total++;
      } else {
        break;
      }
    }
    System.out.println(total);
