java - How to create JSON in Android? -


i want create json string this:

[{"addon_id":2,"addon_rate":1550},{"addon_id":3, "addon_rate":300}]

is possible? how?

my code stands:

string formattedstring = bookingdetailscartadapter.addones_id.tostring().replace("[", "").replace("]", "").trim(); string  formattedstring1 = bookingdetailscartadapter.addones_rate.tostring().replace("[", "").replace("]", "").trim();  myjson="[{\"addon_id\":\""+formattedstring+"\",\"addon_rate\":\""+formattedstring1+"\"}]";

your json means it's array contains 2 objects keys addon_id , addon_rate. both accept number/integer value. first need create jsonarray holds several jsonobjects. have create jsonobjects set keys , values. after need add objects array. jsonarray contains string above print/tostring() it

jsonarray jsonarray = new jsonarray();    jsonobject jsonobjone = new jsonobject(); jsonobjone.put("addon_id", 2); jsonobjone.put("addon_rate", 1550);  jsonobject jsonobjtwo = new jsonobject(); jsonobjtwo.put("addon_id", 3); jsonobjtwo.put("addon_rate", 300);  jsonarray.put(jsonobjone); jsonarray.put(jsonobjtwo);

arrays - What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it? -

what arrayindexoutofboundsexception mean , how rid of it? here code sample triggers exception: string[] name = {"tom", "dick", "harry"}; for(int = 0; i<=name.length; i++) { system.out.print(name[i] +'\n'); } your first port of call should documentation explains reasonably clearly: thrown indicate array has been accessed illegal index. index either negative or greater or equal size of array. so example: int[] array = new int[5]; int boom = array[10]; // throws exception as how avoid it... um, don't that. careful array indexes. one problem people run thinking arrays 1-indexed, e.g. int[] array = new int[5]; // ... populate array here ... (int index = 1; index <= array.length; index++) { system.out.println(array[index]); } that miss out first element (index 0) , throw exception when index 5. valid indexes here 0-4 inclusive. correct, idiomatic for statement here be: for (int index = 0; index <...
