25 Years of IntelliJ IDEA: The IDE That Grew Up With Java (#91)

In this Foojay Podcast, we're celebrating a major milestone in Java development history: 25 years of IntelliJ IDEA.

Think about it: IntelliJ IDEA launched in 2000, and since then, it has become the go-to IDE for millions of Java developers worldwide. From its revolutionary code completion and refactoring tools to AI-powered features and the recent unified Community and Ultimate release, IntelliJ has shaped how we write Java, and keeps reinventing itself to stay ahead.

For this episode, I'm joined by three people from the JetBrains team who know this story inside and out. Marit van Dijk, developer advocate and contributor to the Foojay community. Anton Arhipov, also a developer advocate at JetBrains. And Dmitry Jemerov, who has been part of the IntelliJ IDEA story for a very long time.
