计算文本文件中的字符

Question

I am trying to make a program that reads from a file and counts how many lowercase letters, uppercase letters, whitespace characters (tab, enter etc.) and everything else.

This is the code I have and it shows the right amount of letters but for some reason the "other" counter show way more then it should. Anyone know what I have done wrong?

    File file = new File("C:\\Temp\\Test.txt");
    Scanner s = new Scanner(file).useDelimiter("");

    for (int i = 0; i < file.length(); i++) {
        char c = s.next().charAt(0);

        if (Character.isLetter(c)) {
            if (Character.isLowerCase(c)) {
                isLower++;
            } else {
                isUpper++;
            }
        } else if (Character.isSpaceChar(c) || (c == '\n') || (c == '\t')) {
            isSpace++;
        } else {
            isOther++;
        }

    }

Answer 1

isOther计数器包含\\ r \\ n另外的东西，因为utf8字符乘以2.检查编码并检查文件格式。
