I have been using IntelliJ professionally for the past 5 years and have been fond of debugging tools, the marketplace, and git integration. The auto-complete code suggestion also works like magic for someone who forgets syntax.

- Code recommendations, package selections - Easy of compile & build - Easy to see project structure

It does the routine and repetitive tasks for you by providing clever code completion, static code analysis, and refactorings, and lets you focus on the bright side of software development, making it not only productive but also an enjoyable experience it helps me to maximize my development productivity. it supports all other operating systems also so it provides cross platform consistent experience on different operating systems. its JVM Integration and other supporting tools enhance my developing experince.
