Question

I am trying to have this exact JSON syntax but can’t get to it:

{
    "sun":"yellow",
    "vegetables":[{
        "apple":"red",
        "banana":"yellow",
        "melon":"orange"
    }]
}

The closest I can get is:

{
    "sun":"yellow",
    "vegetables":["{
        "apple":"red",
        "banana":"yellow",
        "melon":"orange"
    "]}
}

This is what I am doing:

JSONObject json = new JSONObject();
json.put("sun","yellow");

ArrayList<HashMap<String,Object>> test = new ArrayList<HashMap<String,Object>>();
HashMap<String,Object> params = new HashMap<String, Object>();
params.put("apple","red");
params.put("banana","yellow");
params.put("melon","orange");

test.add(params);
json.put("fruits",test);

I can’t figure it out, am I missing something?

Answer 1

It should be like this –

JSONObject json = new JSONObject();
json.put("sun","yellow");

JSONArray veg = new JSONArray();
JSONObject vegData = new JSONObject();
vegData.put("apple","red");
vegData.put("banana","yellow");
vegData.put("melon","orange");

veg.put(vegData);   

json.put("vegetables",veg);
