Sorting by some of the fields in Json Object

Question

I have a Josn file containing array of objects like :

{
    \"tId\": \"Something\",
    \"StartTime\": \"05/29/2013 5:28:33 PM\",
    \"CompleteTime\": \"05/29/         


        

Answer 1

You should create a class MyObject to hold a data of one object (tId, startTime, completeTime, status, machineName).

Then, parse each JsonObject to MyObject and add it to a List<MyObject>.

Then, use Collections.sort() and a comparator to sort your list.

Answer 2

Your sorting routine will look something like this, depending on the specifics of how you do your JSON/Object mapping:

Collections.sort(myObjectList, new Comparator<MyObject>() {
  @Override
  int compare(MyObject a, MyObject b) {
    if (a.getStartTime().equals(b.getStartTime())) {
      return a.getMachineName().compare(b.getMachineName());
    }
    return a.getStartTime().compare(b.getStartTime());
  }
});
