IntelliJ IDEA is one of the most popular integrated development environments (IDE). It is used by most Java programmers. When you get a job, you will most likely write code in IntelliJ IDEA. This IDE significantly speeds up the work of the programmer and helps develop a good coding style. To allow you to perfect your skills under real working conditions, we've developed a special plugin for completing CodeGym tasks in IntelliJ IDEA. You can use it right in IntelliJ IDEA to open a list of available incomplete assignments and submit them for verification in one click. You'll learn more about this on the 3rd level of the Java Syntax quest.

There are 2 versions of the program available on the JetBrains website: the paid Ultimate Edition with more advanced functionality and the Community Edition based on open source. While studying on the CodeGym course you will use a free Community Edition.
