What is the purpose of the automatic compilation settings in Idea?

The purpose of the Idea automatic compilation setting is to control whether the Integrated Development Environment (IDE) automatically compiles when the code changes. This setting allows developers to see the results immediately after making code modifications, increasing development efficiency. When the automatic compilation feature is enabled, the IDE will automatically compile the saved file or modified code, converting the modified code into an executable program. This enables developers to quickly verify the correctness of the code and perform debugging and testing. The automatic compilation setting also helps developers quickly identify and fix code errors, improving code quality.
