“More specifically, from JetBrains, the makers of the world-famous IntelliJ IDEA IDE, whose primary claim to fame is its lovely orange, green, purple and black 'Darcula' theme”
This must be a bad attempt at a joke, right? Darcula is a nice theme (I personally prefer high contrast), but surely IntelliJ’s code inspection and automatic refactoring have always been its claim to fame.
Do note that Java has quite a few features now that it didn’t at the time of writing.
