java将数据转成json编码格式技术实例教程(3)_H5之家

{"succList":[
{"aaaa0":0,"bbbb0":0,"cccc0":0},
{"aaaa1":1,"bbbb1":1,"cccc1":1},
{"aaaa2":2,"bbbb2":2,"cccc2":2}
] }

10,json的组合,返回的结果的值是一个数组

Json代码

<table cellpadding="1" cellspacing="1"> <tr> <td bgcolor="#FFE7CE"> 代码如下</td> <td bgcolor="#FFE7CE">复制代码</td> </tr> <tr> <td colspan="2" valign="top" bgcolor="#FFFFFF" id=copy1727>// 创建json的基本对象
String date = "{}";
JSONObject jsonobj = JSONObject.fromObject(date);
String[] str={"json","ajax","Jquery","javascript"};//数组
jsonobj.put("arr", str);
ArrayList<JSONObject> list = new ArrayList<JSONObject>();//创建队列
   for(int i=0; i<3; i ){ //循环
    JSONObject json = JSONObject.fromObject(date); //转化的java
    json.put("aaaa" i, i);
    json.put("bbbb" i, i);
    json.put("cccc" i,str ); //添加一个数组
    list.add(json);
   }
   jsonobj.put("succList", list);
   System.out.println(jsonobj.toString());   </td> </tr> </table>

结果:

{"arr":["json","ajax","Jquery","javascript"],
"succList":[{"aaaa0":0,"bbbb0":0,"cccc0":["json","ajax","Jquery","javascript"]},
{"aaaa1":1,"bbbb1":1,"cccc1":["json","ajax","Jquery","javascript"]},
{"aaaa2":2,"bbbb2":2,"cccc2":["json","ajax","Jquery","javascript"]}
]}

11,组合,任意的嵌套;

Json代码

<table cellpadding="1" cellspacing="1"> <tr> <td bgcolor="#FFE7CE"> 代码如下</td> <td bgcolor="#FFE7CE">复制代码</td> </tr> <tr> <td colspan="2" valign="top" bgcolor="#FFFFFF" id=copy7423>// 创建json的基本对象
    String date = "{}";
    JSONObject jsonobj = JSONObject.fromObject(date);
    String[] str={"json","ajax","Jquery","javascript"};//数组
    //转化java的json嵌套到json中
    JSONObject jsonDemo = JSONObject.fromObject(date);
    for(int n=0;n<3;n ){
        jsonDemo.put("组合" n, n);
    }
    ArrayList<JSONObject> list = new ArrayList<JSONObject>();//创建队列
    for(int i=0; i<3; i ){ //循环
     JSONObject json = JSONObject.fromObject(date); //转化的java
     json.put("aaaa" i, jsonDemo); //嵌套的json
     json.put("bbbb" i, "java");
     json.put("cccc" i,str ); //值为一个数组
     list.add(json);
    }
    jsonobj.put("succList", list);
    System.out.println(jsonobj.toString()); </td> </tr> </table>

运行结果:

{"succList":
[{"aaaa0":{"组合0":0,"组合1":1,"组合2":2},
"bbbb0":"java","cccc0":["json","ajax","Jquery","javascript"]},
{"aaaa1":{"组合0":0,"组合1":1,"组合2":2},
"bbbb1":"java","cccc1":["json","ajax","Jquery","javascript"]},
{"aaaa2":{"组合0":0,"组合1":1,"组合2":2},
"bbbb2":"java","cccc2":["json","ajax","Jquery","javascript"]}
]}

</td> </tr> </table>
