The Java Cookbook is a comprehensive collection of problems, solutions, and practical examples for anyone programming in Java. Developers will find hundreds of tried-and-true Java "recipes" covering all of the major APIs as well as some APIs that aren't as well documented in other Java books.The Java Cookbook, like the bestselling Perl Cookbook, covers a lot of ground, and offers Java developers short, focused pieces of code that can be easily incorporated into other programs. The idea is to focus on things that are useful, tricky, or both. The book includes code segments covering many specialized APIs--like media and servlets--and should serve as a great "jumping-off place" for Java developers who want to get started in areas outside of their specialization.The book provides quick solutions to particular problems that can be incorporated into other programs, but that aren't usually programs in and of themselves.

Descrizione libreria

Welcome to the Solr Books & Books4Cause AbeBooks page! We are a social venture dedicated to supporting social causes, education, and community through a business model. Books4Cause doesn?t raise funds or rely on government grants. All of our funding comes from selling a portion of used books donated to us. Our main goal is to recirculate books back into the hands of people who will read and treasure them. We support both local and global initiatives. Through partnering with the African Library Project, we have built over 120 libraries in nursery schools, elementary schools, high schools, and universities across 18 countries in Africa. Our pop-up free library program in Chicago distributes free books in under-served neighborhoods throughout the city, giving necessary resources to children, adults, and families who otherwise may not have been able to access them. For more information on what we do, or how you can help, go to books4cause.com

Diritto di recesso

Se sei un consumatore, puoi esercitare il tuo diritto di recesso seguendo le istruzioni riportate di seguito. Per "consumatore" si intende qualsiasi persona fisica che agisca per fini che non rientrano nel quadro della sua attivit� commerciale, industriale, artigianale o professionale.

Informazioni relative al diritto di recesso

Diritto di recesso

Hai il diritto di recedere dal presente contratto entro 14 giorni per qualsiasi motivo.

Il periodo di recesso scade dopo 14 giorni dal giorno in cui

tu acquisisci, o un terzo designato diverso dal vettore e da te acquisisce, il possesso fisico dell'ultimo bene o l'ultimo lotto o pezzo.

Per esercitare il diritto di recesso, sei tenuto a informare Solr Books, 7080 N McCormick Blvd, 60712, Lincolnwood, Illinois, U.S.A., della tua decisione di recedere dal presente contratto tramite una dichiarazione esplicita (ad esempio lettera inviata per posta, fax o posta elettronica). A tal fine puoi utilizzare il modulo tipo di recesso, ma non e' obbligatorio. Puoi anche compilare e inviare elettronicamente il modulo tipo di recesso o qualsiasi altra esplicita dichiarazione sul nostro sito web, dalla sezione "Ordini" nel "Mio Account". Nel caso scegliessi questa opzione, ti trasmetteremo senza indugio una conferma di ricevimento su un supporto durevole (ad esempio per posta elettronica).

Per rispettare il termine di recesso, � sufficiente inviare la comunicazione relativa all'esercizio del diritto di recesso prima della scadenza del periodo di recesso.

Effetti del recesso

Se recedi dal presente contratto, ti saranno rimborsati tutti i pagamenti che hai effettuato a nostro favore, compresi i costi di consegna (ad eccezione dei costi supplementari derivanti dalla tua eventuale scelta di un tipo di consegna diverso dal tipo meno costoso di consegna standard da noi offerto). Potremo trattenere dal rimborso le somme derivanti da una diminuzione del valore del prodotto risultante da una tua non necessaria manipolazione.

I rimborsi verranno effettuati senza indebito ritardo e in ogni caso non oltre 14 giorni dal giorno in cui siamo stati informati della tua decisione di recedere dal presente contratto.

Detti rimborsi saranno effettuati utilizzando lo stesso mezzo di pagamento da te usato per la transazione iniziale, salvo che tu non abbia espressamente convenuto altrimenti; in ogni caso, non dovrai sostenere alcun costo quale conseguenza di tale rimborso. Il rimborso pu� essere sospeso fino al ricevimento dei beni oppure fino all'avvenuta dimostrazione da parte tua di aver rispedito i beni, se precedente.

Ti preghiamo di rispedire i beni o di consegnarli a Solr Books, Lincolnwood, Illinois, U.S.A., senza indebiti ritardi e in ogni caso entro 14 giorni dal giorno in cui hai comunicato il tuo recesso dal presente contratto. Il termine � rispettato se rispedisci i beni prima della scadenza del periodo di 14 giorni. I costi diretti della restituzione dei beni saranno a tuo carico. Sei responsabile solo della diminuzione del valore dei beni risultante da una manipolazione del bene diversa da quella necessaria per stabilire la natura, le caratteristiche e il funzionamento dei beni.

Eccezioni al diritto di recesso

Il diritto di recesso non si applica in caso di:

fornitura di giornali, periodici e riviste ad eccezione dei contratti di abbonamento per la fornitura di tali pubblicazioni;
fornitura di contenuto digitale (inclusi applicazioni, MP3, ecc.) mediante un supporto non materiale (per esempio un CD o un DVD) se al momento dell'inoltro dell'ordine hai espressamente consentito all'inizio dell'esecuzione accettando la perdita del diritto di recesso in conseguenza dell'inizio di esecuzione.
