I have json data like this:
{
"err_code": "0",
"date":"20130121",
"time_from":"1242",
"range":"5",
"data":[['12313123','BOOK CODE CYFV3M
NUM CODE 3789850802600'],['089898989','BOOK CODE 1F45MN
NUM CODE 3787510241500']]
}
and I've tried this program:
import org.json.JSONArray;
import org.json.JSONException;
import org.json.JSONObject;
public class JsonKAI {
public static void main(String[] args) {
String jStr = "{\"err_code\":\"0\",\"date\":\"20130121\",\"time_from\":\"1242\",\"range\":\"5\",\"data\":[['12313123','BOOK CODE CYFV3M NUM CODE 3789850802600'],['089898989','BOOK CODE 1F45MN NUM CODE 3787510241500']] }";
// Replace this try catch block for all below subsequent examples
try {
JSONObject rootObject = new JSONObject(jStr);
JSONArray rows = rootObject.getJSONArray("data"); // Get all JSONArray data
int count = rows.length();
for(int i=0 ; i< count; i++){
JSONArray jsonArr = rows.getJSONArray(i);
System.out.println("jsonObject " + i + ": " + jsonArr);
//for(int j=0 ; j< count; j++){
//JSONArray jArr = rows.getJSONArray(j);
//String s = jArr.toString();
//System.out.println("jsonObject " +s);
}}
} catch (JSONException e) {
e.printStackTrace();
}
}
}
The output is:
jsonObject 0: ["12313123","BOOK CODE CYFV3M NUM CODE 3789850802600"]
jsonObject 1: ["089898989","BOOK CODE 1F45MN NUM CODE 3787510241500"]
I wanna ask how to get/parse from ["12313123","BOOK CODE CYFV3M NUM CODE 3789850802600"]
to 12313123
and BOOK CODE CYFV3M NUM CODE 3789850802600
(without '[' and '"')? Please help me. Thank you.
you could try this:
String jStr = "{\"err_code\":\"0\",\"date\":\"20130121\",\"time_from\":\"1242\",\"range\":\"5\",\"data\":[['12313123','BOOK CODE CYFV3M NUM CODE 3789850802600'],['089898989','BOOK CODE 1F45MN NUM CODE 3787510241500']] }";
try {
JSONObject rootObject = JSONObject.fromObject(jStr);
JSONArray rows = rootObject.getJSONArray("data"); // Get all JSONArray data
int count = rows.size();
for (int i = 0; i < count; i++) {
JSONArray jsonArr = rows.getJSONArray(i);
System.out.println("jsonArray " + i + ": " + jsonArr);
for (Object o : jsonArr) {
System.out.println(o);
}
}
} catch (JSONException e) {
}
I have the below example:
String str = "{\"items\":[[1,2,3],[4,5,6],[7,8,9]],\"ans\":[[\"1\",\"2\"],[\"Glad\",\"Good\"]]}";
try{
JSONObject jsonObj = new JSONObject(str);
JSONArray jsonArry1 = jsonObj.getJSONArray("items");
int[][] ints1 = new int[jsonArry1.length()][3];
for(int i = 0; i<jsonArry1.length(); i++){
JSONArray jsa1 = jsonArry1.getJSONArray(i);
for(int j = 0; j<jsa1.length();j++){
ints1[i][j] = jsa1.getInt(j);
}
}
I tested and it works!
