获取字符串字节数方法

//获取字符串字节方法1
public static int getWordCount(String s) {
    int length = 0;
    for (int i = 0; i < s.length(); i++) {
        int ascii = Character.codePointAt(s, i);
        if (ascii >= 0 && ascii <= 255)
            length++;
        else
            length += 2;
    }
    return length;
}

//获取字符串字节方法2 正则表达式
public static int getWordCount2(String s) {
    s = s.replaceAll("[^\\x00-\\xff]", "**");
    int length = s.length();
    return length;
}
