jsonData object

Can someone help, am not sure, where I am going wrong in the attached code. Want to assign the name, publisher and language variables to their values in the jsonData object

JSONChallenge.java 
// A JSONObject variable named 'jsonData'
// was loaded from the data.json file.
String name=jsonData.name;
String publisher=jsonData.publisher;
String language=jsonData.language;
data.json 
{
    "name":"Treehouse Book Series",
    "publisher":"Wiley",
    "language":"English",
    "books":[
        {
            "title":"HTML5 Foundations",
            "author":"Matt West",
            "pages":384
        },
        {
            "title":"CSS3 Foundations",
            "author":"Ian Lunn",
            "pages":352
        }
    ]
}

Hi there,

You need to access the key/value pairs in the dictionary by getting to it with the appropriate accessor. In this case, each value you are brining back is a String, so the getString() method will work fine. You use that method with the jsonData variable that has been set up for you - dot notation will work for this. 

String name = jsonData.getString("name");
String publisher = jsonData.getString("publisher");
String language = jsonData.getString("language");

I hope that makes sense.

Steve.
