The first time I knew about idea was in the summer vacation of 2018, when I installed it and experienced it. At that time, I just got in touch with Java for almost half a year, and I didn’t know eclipse well enough. The only bad thing about IDEA is that it is a bit troublesome to update. If there is no online upgrade, you can only download and reinstall it from the official website. After installation, you have to spend some time to find ways to crack it (of course, you can also support the developers with funds and experience the paid flagship version), and there are few ways to crack it when you update to the latest version. So it is better not to update if you have to, time-consuming and laborious.
