I am using Intellij idea from a long time and I am very happy with it. And now a days it has some great extension that really help. you to write your code more efficiently in team environment and it has now new features of al integration that is very useful features to write and understand the code.

I really like it's code completion especially when you're writing quite obvious code, it's able to detect what the next line should be. It's also great at detecting code smells and a simple "Ctrl + ." Usually provides an accurate solution to fix it

IntelliJ IDEA is one of the best IDEs I've ever user. It makes coding experience smooth with interactive UI that every developer out there will love for sure. Working late in night becomes easy with the pretty dark themes to sooth your eyes while you work for a better tomorrow. Compiler is fast and the autosuggestion is responsive.
