What is JSONArray,JSONObject,JSONStringer and JSONTokenizer

Question

I'm new to Android. I have learnt some basic concepts in Android. Now I'm learning JSON, I wanted to know the definitions of JSONArray,JSONObject,JSONStringer and JSONTokenizer. I'm a bit confused with these terms.Can anyone provide me the correct definition for these terms??

Thanks

Answer 1

json array:

 [
   {
      "id":711
   },   {
      "id":712
   }
]

json object:

 {
      "id":711
   }

1) Array([) In a JSON file , square bracket ([) represents a JSON array.

2) Objects({) In a JSON file, curly bracket ({) represents a JSON object.

3) Key A JSON object contains a key that is just a string. Pairs of key/value make up a JSON object.

4) Value Each key has a value that could be string , integer or double e.t.c
