How can I configure the JDK compilation version for the idea?

To set the JDK compilation version, you can follow these steps:

1. Open the command line interface.
2. Use the command java -version to check the current Java version.
3. If you need to change the Java version, you can download and install the corresponding version of JDK.
4. After installation, add the installation directory to the system’s environment variables. On Windows, this can be done in Control Panel -> System and Security -> System -> Advanced system settings -> Environment Variables. Add the JDK installation directory to the system’s PATH variable.
5. Open the command line interface and enter the command “java -version” to verify if the new Java version is in effect.
6. If you need to use different JDK versions in a specific project, you can set it in the project’s build configuration. The specific steps depend on the build tool you are using, such as Maven, Gradle, etc.

It is important to note that the JDK compiler version can be configured in different IDEs. For example, in Eclipse, you can set the JDK version in the project properties, while in IntelliJ IDEA, you can configure it in the project settings.

I hope these steps can help you set up the JDK compilation version.
