Java™ 18 & 19. What's new and noteworthy?
Deep Dive (BEGINNER level)

Hey, there are two major Java versions released every year! We don’t have to wait 3 years or so for new features any more. Isn’t that cool? 😉

Java was supposed "to be slow". However, Java turns out to evolve so fast, that next releases aren't just version bumps, but might significantly change the rules of the game. That's a good reason to check out what's new in Java.

To name a few changes:

  • Pattern Matching for switch,
  • Record Patterns,
  • Virtual Threads,
  • Calling native stuff,
  • Simple Web server,
  • what's gone and what will be gone,
  • and other stuff.

If you find them interesting, let’s dive deep together into new interesting stuff.

Before Docker, configuring the environment for integration testing was painful - people were using fake database implementations, mocking servers, usually it was not cross-platform as well. However, than to Docker, now we can quickly prepare the environment for our tests.

In this lab, I would like to show how you can use Testcontainers - a popular testing library that harnesses Docker to easily, reliably, spin up test dependencies.

You’ll go through the process adding powerful integration tests to your codebase (we’ll use a Spring Boot app) without the headache of managing external service dependencies manually. And get acquainted with all necessary Testcontainers concepts to write elegant, efficient, and reliable integration tests.
