arrays - Store multiple values in single key in json

Question

I need to store many values in single key of json. e.g.

{
  "number" : "1","2","3",
  "alphabet" : "a", "b", "c"
}

Something like this. Any pointers?

Answer 1

Use arrays:

{
    "number": ["1", "2", "3"],
    "alphabet": ["a", "b", "c"]
}

You can the access the different values from their position in the array. Counting starts at left of array at 0. myJsonObject["number"][0] == 1 or myJsonObject["alphabet"][2] == 'c'
