字符串如下 [["5395722","527781","aaaa"],["5395722","527781","bbb"],["5395722","527781","bbb"]] 要一行一行的

public static void main(String[] args) throws Exception{
        String str="[[\"5395722\",\"527781\",\"aaaa\"],[\"5395722\",\"527781\",\"bbb\"],[\"5395722\",\"527781\",\"bbb\"]]";
        Pattern pat=Pattern.compile("\\\"(.*?)\\\"");
        Matcher m=pat.matcher(str);
        ArrayList list=new ArrayList();
        while(m.find()){
            Person p = new Person(); 
            p.setUserName(m.group(1)); //每一个[]中的第一个值 
            if (m.find()){
                p.setUserPass(m.group(1)); //每一个[]中的第二个值 
            }
