Eclipse and NetBeans do exist, and... ehhhhh. I used NetBeans for a long time; couldn't stand Eclipse; and these days I only use IntelliJ. But the others absolutely exist, and it'd be hard to say that Apache and the Eclipse Foundation aren't deeply embedded in the Java ecosystem.
Eclipse is fine. Especially from VsCode where it uses the Eclipse language server. It boots fast, and when you run it with a modern JVM and GC the memory usage is leagues lower than IntelliJ.
