Google books API searching by ISBN

I am trying to figure out how to search for a book by ISBN using the Google Books API. I need to write a program that searches for an ISBN then prints out the title, author, and edition. I tried using List volumesList = books.volumes.list("");
but that did not allow me to search by ISBN and I did not see a way to get the information I needed(when an ISBN was placed in it had no results) . What I have right now is:
JsonFactory jsonFactory = new JacksonFactory();
final Books books = new Books(new NetHttpTransport(), jsonFactory);
List volumesList = books.volumes.list("9780262140874");
volumesList.setMaxResults((long) 2);
volumesList.setFilter("ebooks");
try
{
Volumes volumes = volumesList.execute();
for (Volume volume : volumes.getItems())
{
VolumeVolumeInfo volumeInfomation = volume.getVolumeInfo();
System.out.println("Title: " + volumeInfomation.getTitle());
System.out.println("Id: " + volume.getId());
System.out.println("Authors: " + volumeInfomation.getAuthors());
System.out.println("date published: " + volumeInfomation.getPublishedDate());
System.out.println();
}
} catch (Exception ex) {
// TODO Auto-generated catch block
System.out.println("didnt wrork "+ex.toString());
}
If anyone has any suggestions about how to make this more efficient let me know. New Code:
String titleBook="";
////////////////////////////////////////////////
try
{
BooksService booksService = new BooksService("UAH");
String isbn = "9780262140874";
URL url = new URL("http://www.google.com/books/feeds/volumes/?q=ISBN%3C" + isbn + "%3E");
VolumeQuery volumeQuery = new VolumeQuery(url);
VolumeFeed volumeFeed = booksService.query(volumeQuery, VolumeFeed.class);
VolumeEntry bookInfo=volumeFeed.getEntries().get(0);
System.out.println("Title: " + bookInfo.getTitles().get(0));
System.out.println("Id: " + bookInfo.getId());
System.out.println("Authors: " + bookInfo.getAuthors());
System.out.println("Version: " + bookInfo.getVersionId());
System.out.println("Description: "+bookInfo.getDescriptions()+"\n");
titleBook= bookInfo.getTitles().get(0).toString();
titleBook=(String) titleBook.subSequence(titleBook.indexOf("="), titleBook.length()-1);
}catch(Exception ex){System.out.println(ex.getMessage());}
/////////////////////////////////////////////////
JsonFactory jsonFactory = new JacksonFactory();

System.out.println("Authors: " + volumeInfomation.getAuthors());
System.out.println("date published: " + volumeInfomation.getPublishedDate());
System.out.println();
} catch (Exception ex) {
System.out.println("didnt wrork "+ex.toString());
}
Solución
Are you using the deprecated data API?
With Books API v1 (from Labs) you could use the query
https://www.googleapis.com/books/v1/volumes?q=isbn:<your_isbn_here>
for example
https://www.googleapis.com/books/v1/volumes?q=isbn:0735619670
to query a book by its ISBN.
You may want to look at Googles example code: BooksSample.java

Can't you try like this as said in the developers guide developer guide if I did understand your task. You can do like this :
BooksService booksService = new BooksService("myCompany-myApp-1");
myService.setUserCredentials("user@domain.com", "secretPassword");
String isbn = "9780552152679";
URL url = new URL("http://www.google.com/books/feeds/volumes/?q=ISBN%3C" + isbn + "%3E");
VolumeQuery volumeQuery = new VolumeQuery(url);
VolumeFeed volumeFeed = booksService.query(volumeQuery, VolumeFeed.class);
// using an ISBN in query gives only one entry in VolumeFeed
List<VolumeEntry> volumeEntries = volumeFeed.getEntries();
VolumeEntry entry = volumeEntries.get(0);
Now using the VolumeEntry api look for your desired getXXXX() and use it in your code.I hope it will help you to solve your problem.
$("form").submit(
function(e) {
e.preventDefault();
var isbn = $('#ISBN').val();
var isbn_without_hyphens = isbn.replace(/-/g, "");
var googleAPI = "https://www.googleapis.com/books/v1/volumes?q=" + isbn_without_hyphens;
$.getJSON(googleAPI, function(response) {
if (typeof response.items === "undefined") {
alert("No books match that ISBN.")
} else {
$("#title").html(response.items[0].volumeInfo.title);
$("#author").html(response.items[0].volumeInfo.authors[0]);
$("#publishedDate").html(response.items[0].volumeInfo.publishedDate);
}
});
}
);
