有一个二维数组如下：
String[][]grid={
{"cg_id","cg_name","cg_order","tq_id","tq_name","tq_kind","tq_score","tq_order","op_id","op_name","op_length","op_kind","op_order"},

{"2","互联网的坏处","2","15"," 互联网对谁的伤害最大","单选","10.00","2","27","儿童","1000","radio","1"},

{"2"," 互联网的坏处","2","15"," 互联网对谁的伤害最大","单选","10.00","2","28","青少年","1000","radio","2"},

{"2"," 互联网的坏处","2","15"," 互联网对谁的伤害最大","单选","10.00","2","29","中年","1000","radio","3"},

{"1"," 互联网的好处","1","17"," 性能","简答","10.00","1","31","答","1000","textarea","1"},

{"1"," 互联网的好处","1","16"," 作用","填空","10.00","2","30","答","1000","text","1"}
}
在此二维数组中：cg_id:表示目录号，cg_name:表示目录名称；tq_id:表示试题号，tq_name:表示试题名称；op_id:表示选项号，op_name:表示选项名称
从此二维数组中，大概可以知道目录有两个：互联网的坏处和好处
在互联网的坏处目录下有一道试题：互联网对谁的伤害最大；
在此试题下有三个选项：儿童、青少年、中年；
在互联网的好处目录下有两道试题作用、和性能，分别有一个选项：答；
怎样用一个for循环能让人一目了然的看出这些包含关系，并且要求是动态的，当有目录或试题，选项，增加时，这些关系还适合
就是用FOR循环输出共有几个目录，每个目录下有几道题，每个试题下有什么选项，当有目录或试题，选项，增加时，这些关系还适合

这个好像和for循环没什么关系，你需要考虑的是怎么去写好这几个model类,将非明确关系的二维数据转换成能表现出父子关系的model。

class 目录 {
      private String 目录号;
      private String 目录名称;
      private Integer 目录Order;
      private List<题目> list;
}

class 题目 {
      private 目录 parent目录；
       private String 题目号;
      private String 题目名称;
      private Integer 题目Order;
      private String 题目类型；
       private Integer 题目总分；
      private List<选项> list;
}

class 选项 {
      private 题目 parent题目;
      ...
}
