Real World Java 9

Trisha Gee, developer advocate at JetBrains talks about new interesting features of Java 9
15 October 2017   2126

The feature we always hear about whenever Java 9 is in the news is Jigsaw, modularity. But this doesn't scratch the same developer itch that Java 8's lambdas and streams did, and we're left with a vague sensation that the next version might not be that interesting.

Java 9 actually has a lot of great additions and changes to make development a bit nicer. These features can't be lumped under an umbrella term like Java 8's lambdas and streams, the changes are scattered throughout the APIs and language features that we regularly use.

In this presentation Trisha Gee shows, via live coding:

  • What the Java Platform Module System is and how to make your code modular
  • How we can use the new Flow API to utilise Reactive Programming
  • The improvements to the Streams API that make it easier to control infinite streams
  • How to the Collections convenience methods simplify code

Along the way we bump into other Java 9 features, including some of the additions to interfaces and changes to deprecation.

TIOBE Index June 2019 to be Rolled Out

Java is still on the top, but experts noted fast growth of Python search queries, and they believe it can reach 1st place in 3-4 years

June 2019 TIOBE Index has been released. Analysts noted a sharp increase in the proportion of searches for Python.

This month Python has reached again an all time high in TIOBE index of 8.5%. If Python can keep this pace, it will probably replace C and Java in 3 to 4 years time, thus becoming the most popular programming language of the world. The main reason for this is that software engineering is booming. It attracts lots of newcomers to the field. Java's way of programming is too verbose for beginners. In order to fully understand and run a simple program such as "hello world" in Java you need to have knowledge of classes, static methods and packages. In C this is a bit easier, but then you will be hit in the face with explicit memory management. In Python this is just a one-liner.

Experts attributed the growing popularity of Python to the fact that now many have hit the development of software. And newcomers prefer Python - succinct and concise. According to analysts, Java for beginners is too verbose, and C sooner or later will force to understand the intricacies of memory management.
