Članak – Java Tutorial Updated!

10.03.2013. autora/ice HUJAK

Kako je objavljeno na blogu Java Tutoriala, isti je osvježen Java Tutorial Updated! (The Java Tutorials’ Weblog).

Prenosimo ukratko novosti koje se odnose na Java SE 8, a napominjemo da je isti (zasad) dostupan samo online.

Lambda expressions, a result of the work of Project Lambda, are a feature being added to the JDK 8 release of the Java platform. Lambda expressions support programming in a multicore environment by adding closures and related features to the Java language. An early access page on Lambda Expressions is part of this tutorial release. As part of this work, the information on Nested Classes, Anonymous Classes, and Local Classes have been updated and a new page on When to Use Nested Classes, Local Classes, Anonymous Classes, and Lambda Expressions has been added.
The Annotations page has been moved and expanded to be a full Annotations lesson. The new lesson includes information on Java SE 8 features: Type Annotations, which can be used in conjunction with pluggable type systems for improved type checking, and Repeating Annotations.
The lesson Service Providers for Internationalization includes the new section Installing a Custom Resource Bundle as an Extension, which shows you how to load resource bundles with service provider interfaces (SPIs). These interfaces enable you to create applications that you can extend, through plug-ins or modules, without modifying their original code base. See the new section Creating Extensible Applications for more information.

Knjige – The Java Series Series i novi Java Tutorial

10.03.2013. autora/ice HUJAK

Još od 1996. Addison-Wesley objavljuje seriju knjiga The Java Series , a sada je objavljen i The Java Tutorial u 5. izdanju zasnovan na Java SE 7. Sadrži niz novosti uključivo novi file I/O API (NIO.2) kao i migraciju, try-with-resources statement, binary literals, diamond syntax, osvježeni generics tutorial, te dio o certifikaciji.

Ako znate nekoga tko tek uči Javu ovo može biti vrlo korisno. Prenosimo dio opisa:

This revised and updated edition introduces the new features added to the platform, including a section on NIO.2, the new file I/O API, and information on migrating legacy code to the new API. The deployment coverage has also been expanded, with new chapters such as “Doing More with Rich Internet Applications” and “Deployment in Depth,” and a section on the fork/join feature has been added to the chapter on concurrency. Information reflecting Project Coin developments, including the new try-with-resources statement, the ability to catch more than one type of exception with a single exception handler, support for binary literals, and diamond syntax, which results in cleaner generics code, has been added where appropriate.

The chapters covering generics, Java Web Start, and applets have also been updated. In addition, if you plan to take one of the Java SE 7 certification exams, this guide can help. A special appendix, “Preparing for Java Programming Language Certification,” lists the three exams available, details the items covered on each exam, and provides cross-references to where more information about each topic appears in the text. All of the material has been thoroughly reviewed by members of Oracle Java engineering to ensure that the information is accurate and up to date.

Trenutno je aktualan i discount code DUKE2013 koji štedi $10 na knjige iz Java Series.

Vijest – JAXConf 2013 goes free

10.03.2013. autora/ice HUJAK

Na blogu konferencije JAXConf u Santa Clari, koja se nekim slučajem događa istovremeno kad i hrvatska konferencija JavaCro :-), objavljeno je kako je od ove godine potpuno besplatna za sudionike The road to JAX • JAXConf 2013 goes free, a smanjenje su i cijene workshopa. Ako vas put nanese u Santa Claru početkom lipnja (iako očekujemo da ste u to doba u Tuhelju 🙂 ) predlažemo da svakako posjetiti JAXConf.

U HUJAK-u svakako pozdravljamo ovu odluku i nadamo se da će takav slučaj jednog dana biti i s našom konferencijom (kada se nađe dovoljno sponzora koji će pokriti sve troškove), kao i da će pojeftiniti najpoznatije svjetske Java konferencije poput JavaOne (za koju smo prošle godine izdvojili između $1600 i $2000 za kotizacije).
