The problem is how to put the multiple values of a key to a json object. Like key2 and key3 in above example. Single value we can do. — Ramesh, Jan 05 '18 at 09:12

Put your "Arguments" into a class, I'm going to call it Argument. Then use Gson to serialise this class to JSON.

Like the following:

Gson gson = new GsonBuilder().setPrettyPrinting().create();
String response = gson.toJson(argumentInstance);
Files.write(path, Arrays.asList(response.split("\n")));

You can then read it back like so, providing the class:

Gson gson = new Gson();
argumentInstance = gson.fromJson(Files.newBufferedReader(path), Argument);
