With jsonBooks defined as:

JSONArray jsonBooks = jsonData.getJSONArray("books");

You could translate it as, "From the JSON array "books", give me the element at index i which is a JSON object."

{
    "name":"Treehouse Book Series",
    "publisher":"Wiley",
    "language":"English",
    //From this array
    "books":[ 
         //At i = 0
        { 
            "title":"HTML5 Foundations",
            "author":"Matt West",
            "pages":384
        },
        //At i = 1
        {
            "title":"CSS3 Foundations",
            "author":"Ian Lunn",
            "pages":352
        }
    ]
}

Note that the comments I added will cause problems in an actual JSON file.
