Parse JSON in it's order the way it is

Question

I am parsing a JSON file with weekdays and times inside those weekdays. Problem is that whenever I parse them, it's a huge mix up. For example this is my json file:

{
"root1": {
"test": {
  "monday": {
    "08:00-12:20": {
      "value1": "value2",
      "value3": "value4"
    }
  },
  "tuesday": {
    "08:00-11:50": {
      "value1": "value2",
      "value3": "value4"
    }
  },
  "wednesday": {
    "08:00-11:50": {
      "value1": "value2",
      "value3": "value4"
    }
  },
  "friday": {
    "08:00-11:50": {
      "value1": "value2",
      "value3": "value4"
    }
  }
},
"test2": {
  "saturday": {
    "08:05-11:00": {
      "value1": "value2",
      "value3": "value4"
    }
  }
},
"test3": {
  "monday": {
    "12:45-15:10": {
      "value1": "value2",
      "value3": "value4"
    }
  },
  "tuesday": {
    "08:55-11:50": {
      "value1": "value2",
      "value3": "value4"
    },
    "15:30-17:55": {
      "value1": "value2",
      "value3": "value4"
    }
  },
  "wednesday": {
    "16:35-18:00": {
      "value1": "value2",
      "value3": "value4"
    }
  },
  "thursday": {
    "08:00-09:40": {
      "value1": "value2",
      "value3": "value4"
    },
    "10:00-12:25": {
      "value1": "value2",
      "value3": "value4"
    }
  },
  "friday": {
    "16:35-18:00": {
      "value1": "value2",
      "value3": "value4"
    }
  }
}
}
}

So you see the weekdays are in the correct order. But if I parsed them they're like this for example:

thursday
friday
monday
wednesday
tuesday

How can I parse them into the right order?

Following the JSON specification, [objects are unordered](http://stackoverflow.com/a/4920304/1073063). — Pablo, Jun 07 '13 at 08:41
Ok thanks. But how can I parse them into the right order? Or sort them? — user754730, Jun 07 '13 at 08:43
You probably can't, unless there is some implementation that doesn't follow the specification. You'll have to order them yourself after parsing the file. If you want ordered results, you should use arrays. — Pablo, Jun 07 '13 at 08:47

You can use JsonReader for stream reading - and control order.

you have to use a JSONArray instead of a JSONObject. In fact the JSONArray preserves the order

Also if that is not an array? – Enrichman Jun 07 '13 at 08:54

I understand the point, but in JSON this is an Object `{..}` and this is an array `[..]`. I don't think you can use a JSONArray to deserialize JSON objects.. – Enrichman Jun 07 '13 at 08:59
