Java – how to extract values from JSON

I get a response string from the server, as shown below

{"name":"Json","detail":{"first_name":"Json","last_name":"Scott","age":"23"},"status":"success"}

I want the value of the name How can I do this? Thank you in advance

Solution

Look at this code. What do I use in my application

String data="{'foo':'bar','coolness':2.0,'altitude':39000,'pilot':{'firstName':'Buzz','lastName':'Aldrin'},'mission':'apollo 11'}";

I search like this

JSONObject json = (JSONObject) JSONSerializer.toJSON(data);        
    double coolness = json.getDouble( "coolness" );
    int altitude = json.getInt( "altitude" );
    JSONObject pilot = json.getJSONObject("pilot");
    String firstName = pilot.getString("firstName");
    String lastName = pilot.getString("lastName");

    System.out.println( "Coolness: " + coolness );
    System.out.println( "Altitude: " + altitude );
    System.out.println( "Pilot: " + lastName );
