Foojay Podcast #66: Let's Talk About Java Code!
In this Foojay podcast, we dive into a few articles that were published recently and focus on code.
- Igor Kulakov of JetBrains gives us his insights into the tool he created to find duplicate content in documentation.
- Rijo Sam explains how you can generate real random values and how he created a train departure display.
- Maxillian Arruda explains in a very detailed post the different ways to construct a complex Java object.
- And we start with Wim De Troye about the code changes he had to do in a project that got upgraded from Spring Boot 2 to 3.
