Treves the JSON object and manipulate the value in java

Question

What im trying to do is

JSON:

{
aKey:{
        aChildKey:""
     },
bKey:""
}

aKey:{
        aChildKey:"aKey.aChildKey"

You need to deserialize the JSON into an object, set the values, then serialize it back into JSON. There are a number of libraries you can use for this, like org.json, gson, or Jackson. Those libraries also allow you to modify the value directly. For example, using org.json, you can do something like this:

JSONObject jsonObject = new JSONObject(myJsonString);
jsonObject.getJSONObject("akey").put("aChildKey","aKey.aChildKey");
