July in Java: Spring 5, Pattern Matching, and Doubting OOP

Now that the smoke has cleared from the JPMS debate, let's touch on Java 9, Spring 5, Optionals, Java's ranking in the TIOBE Index, and more.

Well, it hasn't been quite as exciting a month as it was in May and June, but there's still plenty to talk about in the Java-sphere! Let's take a look at what you should know in the Java world in order to be ready for the next big things.

Coffee Break!

  1. What's New in Spring Framework 5? by John Thompson. Anyone who's remotely interested in Spring has had their eye on Spring 5 for a while now. Here's a breakdown of the biggest changes coming to Spring 5 from functional programming to library support to all the JDK updates. 

  2. 4 Techniques for Writing Better Java, by Justin Albano. This is a great summary of four ways to keep your code clean when using covariant return types, intersectional generic types, auto-closeable classes, and final classes and methods. 

  3. Beginning to Doubt Object-Oriented Programming, by Grzegorz Ziemoński. Grzegorz, DZone's Java Zone Leader, talks about his experimentation with functional programming in the Java world. In the end, it's a great message that shows how doubt can actually lead to affirmed beliefs and the importance of trying new things before dismissing them.

  4. Separating Microservices: Hype and Reality for Pragmatic Java Programmers, by Reza Rahman. This article, written Java EE Guardian Reza Rahman, is a great look at how Java programmers can separate the hype from the help that microservices can offer.

  5. Optional Anti-Patterns, by Przemyslaw Magda. Want to make sure you're using Optionals the right way? Make sure your favorite Java 8 null-checking tactic (assuming you're using Optionals, of course) doesn't fall into these traps.

Jumping From Java?

While next month's launch of Java 9 will likely see a rebound, it's interesting to note that the language took a 6 percent hit year-over-year, according to the TIOBE Index. Is Java dying? No, of course not — at least not yet (nothing lasts forever, after all) — but if you're on the fence about learning a new language, take a look at what some of the up-and-comers might be.

Adventures in Pattern Matching!

If you've got an interest in bringing pattern matching to Java (and a spare 53 minutes), Java Language Architect Brian Goetz held a talk at the JVM Language Summit that's garnering some positive attention. Take a look at his approaches to making code less verbose and error-prone.

Java 9 Is Coming. (No, Really This Time. Probably.) Are You Ready?

It's not news that, in June, Java 9's release date was pushed back to September. But if you've got the time, it might be worthwhile to head over to OpenJDK to check out your favorite JEPs as well as the remaining bugs that need to be squashed en route to Java 9's launch.
