Welcome Java 9!<\/a>\u00a0Members of the community talk about their favourite features and how Java 9 will impact developers.<\/li>\n<\/ul>\nBeyond Java 9<\/h2>\n
Yes, already… and the future is much closer than you thought!<\/p>\n
\n- Moving Java Forward Faster<\/a>.\u00a0 Yes, you read that right.\u00a0 JDK 10<\/a>\u00a0is\u00a0coming out in March<\/a> 2018.\u00a0 That’s this March!\u00a0 Except that it will probably be called Java 18.3.\u00a0\u00a0It’s even already going through the JCP process<\/a>.<\/li>\n
- Changes to the JDK release model<\/a>, more details on the new release schedule (video)<\/li>\n
- Java Community Process Reacts to Release Cycle Announcement<\/a><\/li>\n
- Java: Free At Last<\/a>,\u00a0specifically looking at the changes to licensing for Java.<\/li>\n
- Oracle Consolidates the OpenJDK 10 Repository Forest<\/a>,<\/li>\n
- Local-Variable Type Inference proposed to target JDK 10<\/a>,\u00a0another great feature to reduce boilerplate and one I can’t wait to use.<\/li>\n
- Brian Goetz Speaks to InfoQ on Pattern Matching for Java<\/a>, for more details about the suggested feature see the document on java.net<\/a>.<\/li>\n<\/ul>\n
Java<\/h2>\n
Despite all the Java 9 noise, there were a number of excellent non-Java-9 articles and tutorials this month, although even these\u00a0have occasional nods to new functionality in Java 9.<\/p>\n
\n- Handling checked exceptions in Java streams<\/a>, and it’s worth checking out Ken’s new book Modern Java Recipes<\/a>\u00a0which will help you use some of the new features in Java 8 and 9 (full disclosure, I wrote the Foreword for the book).<\/li>\n
- Ken Kousen on Java, Spring, and Groovy<\/a>, the author of the above talking about a whole bunch of things that’s relevant to the modern developer (podcast).<\/li>\n
- Finally Getting the Most out of the Java Thread Pool<\/a><\/li>\n
- Why does my code throw a null pointer exception?<\/a>\u00a0in the context of writing tests.<\/li>\n
- Following OOP principles – hermetization<\/a>, a look at pre-Java-9 data hiding. Modules<\/a>, of course, provide an additional mechanism for hiding classes and packages.<\/li>\n
- Weak, Soft, and Phantom References in Java (and Why They Matter)<\/a>, we should understand the Garbage Collector if we want to know what impact\u00a0it might have if your application is now using G1 by default<\/a>. For more details see Oracle’s\u00a0Getting Started with the G1 Garbage Collector<\/a>.<\/li>\n
- How to Format a String, Clarified!<\/a> A nice back-to-basics summary of String formatting.<\/li>\n
- Understanding Classes in Java (Part 1)<\/a> Another good back-to-basics article. You probably know all of this but it’s always worth\u00a0revising topics like this.\u00a0\u00a0Understanding Classes in Java (Part 2)<\/a>\u00a0goes deeper, including the representation of Objects in memory.<\/li>\n<\/ul>\n
Android<\/h2>\n
I get a lot of my Android news from the excellent Android Weekly newsletter<\/a>, where they link to\u00a0a much wider range of Android articles than I do,\u00a0so it’s well worth subscribing if Android is your thing.<\/p>\n\n- Beautiful, Performant Android UI<\/a><\/li>\n
- Android Architecture Components: Testing your ViewModel LiveData<\/a><\/li>\n
- Is your Android Library, Lifecycle-Aware?<\/a><\/li>\n
- ConstraintLayout\u00a0\u2013 Guidelines, Barriers, Chains\u00a0and Groups<\/a><\/li>\n
- Making the most out of Android Studio Debugger<\/a><\/li>\n
- Exploring Background Execution Limits on Android Oreo<\/a><\/li>\n

- Optimize your Android apps for Chromebooks<\/a><\/li>\n
- The Dark side of Fragments<\/a><\/li>\n
- Hide your crashes gracefully (and still report them)<\/a><\/li>\n<\/ul>\n
Languages, Frameworks and Libraries<\/h2>\n
The other big news was the release of Java EE 8<\/a> at last\u00a0too, as well as more news on its move to Open Source.\u00a0 RebelLabs also released their annual productivity report, which\u00a0shouldn’t be ignored even despite all the other Java noise, particularly since it contains good news for JetBrains and our users.<\/p>\n\n- Java EE 8 and GlassFish 5.0 Released<\/a>! Check out the\u00a0First Cup of Java EE Tutorial Project<\/a>.<\/li>\n
- About Java EE 8, JAX-RS, JSON API, and Mobile Apps<\/a> (videos).<\/li>\n
- Oracle Chooses Eclipse Foundation as New Home for Java EE<\/a><\/li>\n
- RebelLabs Developer Productivity Report 2017: Why do you use the Java tools you use?<\/a>\u00a0The highlight for us is that IntelliJ IDEA usage is up again, and Kotlin made it into the top 6 languages (and has the highest satisfaction rating).<\/li>\n
- Using buildSrc for custom logic in Gradle builds<\/a><\/li>\n
- Creating a REST Web Service With Java and Spring (Part 1)<\/a><\/li>\n

#WorksFineOnJDK9<\/a>:<\/p>\n\n- JUnit 5.0 released<\/a>! If you haven’t tried it yet, do give it a\u00a0go it addresses a lot of the weaknesses of JUnit 4.\u00a0 I’m personally using it on Java 9 and it’s\u00a0perfect.<\/li>\n
- Gradle 4.2<\/a> is out.\u00a0 Gradle 4.1<\/a> had support for Java 9, but you’ll probably want to use the latest Gradle release if you want the best support. Also check out the\u00a0Building Java 9 Modules<\/a> tutorial.<\/li>\n
- Spring Framework 5.0 goes GA<\/a>, with support for Java 9 and\u00a0Java EE 8 API level. You may also want to check out\u00a0This Week in Spring, Java 9 Edition<\/a>.<\/li>\n
- Akka 2.5.6 Released\u00a0– with JDK9 and j.u.c.Flow support<\/a>. It’s exciting to see a Reactive Library with support for the new Java 9 Reactive API<\/a> already.<\/li>\n
- Hibernate ORM 5.2.11.Final released<\/a>, and is Java 9 ready<\/a>.<\/li>\n<\/ul>\n
