Intellij Idea - Installation and Configuration

在本节中，我们将了解如何安装和配置 IntelliJ IDEA。这个过程的第一步是从选择版本开始。根据您的需要，您可以下载社区版或旗舰版。顾名思义，社区版绝对免费，并且我们也可以用它进行商业开发。然而，旗舰版是付费版本，我们可以免费评估 30 天。

In this chapter, we will understand how to install and configure IntelliJ IDEA. The first step of the process starts with choosing the edition. As per your requirements, you can download community or ultimate edition. As name suggests, community edition is absolutely free and we can use it for commercial development as well. However, ultimate edition is paid version and we can evaluate it freely for 30 days.
