java 分隔符 字符串转换字符串数组

//字符串转换字符串数组public static String[] split(String source){        if(source == null || source.trim().equals("")) return null;        //‘,’作为分隔符        StringTokenizer commaToker = new StringTokenizer(source, ", ");        String[] result = new String[commaToker.countTokens()];        int m=0;        while(commaToker.hasMoreTokens()){            result[m] = commaToker.nextToken();            m++;        }        return result;    }

String[] arr = str.split(",");
