JSONObject and JSONArray parsing json data in Android_PHP tutorial

Today I will introduce about json data parsing. We use JSONObject and JSONArray in Android to parse json data. Friends who have android development can refer to it.

String strJson = "{"students":[{"name":"Jack","age":12}, {"name":"Vista","age":23}, {"name": "Kaka","age":22}, {"name":"Hony","age":31}]}";
         try {
                JSONObject jo = new JSONObject(strJson);
JSONArray jsonArray = (JSONArray) jo.get("students");
for (int i = 0; i < jsonArray.length(); ++i) {
                     JSONObject o = (JSONObject) jsonArray.get(i);
System.out.println("name:" + o.getString("name") + "," + "age:"
+ o.getInt("age"));
            }
           } catch (JSONException e) {
              e.printStackTrace();
}

2. Use JsonReader in gson to parse json data

try {
            String string = "{"class":1, "students":[{"name":"jack", "age":21},{"name":"kaka", "age":21},{"name":"lucy", "age":21}]}";
            StringReader sr = new StringReader(string);
            JsonReader jr = new JsonReader(sr);
            jr.beginObject();
            if (jr.nextName().contains("class")) {
                System.out.println("班级: " + jr.nextString());
                if (jr.nextName().equals("students")) {
                    jr.beginArray();
                    while (jr.hasNext()) {
                        jr.beginObject();
                        if (jr.nextName().equals("name"))
                            System.out.print("姓名：" + jr.nextString());
                        if (jr.nextName().equals("age")) {
                            System.out.println(" , 年龄：" + jr.nextInt());
                        }
                        jr.endObject();
                    }
                    jr.endArray();
                }
            }
            jr.endObject();
        } catch (FileNotFoundException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
