How to convert jsonString to JSONObject in Java

I have String variable called jsonString:
{"phonetype":"N95","cat":"WP"}


Now I want to convert it into JSON Object. I searched more on Google but didn't get any expected answers!

Using org.json library:

try {
     JSONObject jsonObject = new JSONObject("{\"phonetype\":\"N95\",\"cat\":\"WP\"}");
}catch (JSONException err){
     Log.d("Error", err.toString());
}
