StringTokenizer与split用,分割字符串

    public static void main(String[] args) throws Exception {
        String string = "aa,,cc,,";
        StringTokenizer st = new StringTokenizer(string, ",");
        String[] strs = string.split(",");

        for (int i = 0; i < 5; i++) {
            if (st.hasMoreTokens()) {
                System.out.println("Token:" + st.nextToken());
            }else {
                System.out.println("Token:null");
            }
        }
        for (int i = 0; i < strs.length; i++) {
            if ("".equals(strs[i])) {
                System.out.println("split:empty");
            } else {
                System.out.println("split:" + strs[i]);
            }
        }
    }

输出结果

Token:aa
Token:cc
Token:null
Token:null
Token:null
split:aa
split:empty
split:cc
