In the Project Structure dialog Ctrl+Alt+Shift+S , select SDKs. Select the necessary JDK version if you have several JDKs configured, and open the Documentation Path tab on the right.
IntelliJ IDEA First Java Program. 1 1. Create Project. Start IntelliJ IDE. Go to File -> New -> Project. The below screen appears. Select The Java Project and appropriate Project SDK. 2 2. Create Package. 3 3. Create Java Class. 4 4. Run Application.
You can run applications right from IntelliJ IDEA if you have an SDK set up for your project / module. If you are not going to pass any parameters to your program, and your program does not require any specific actions to be performed before start, you can run it right from the editor.
We are going to write and execute Hello World program. 1. Create Project Start IntelliJ IDE. Go to File -> New -> Project. The below screen appears. Select The Java Project and appropriate Project SDK. Click Next. Now, Type the Project name and select Project location. Click Finish. Once we click on Finish Button, the following screen will open. 2.
Create a run configuration for the packaged application. To run a Java application packaged in a JAR, IntelliJ IDEA allows you to create a dedicated run configuration. Press Ctrl+Shift+A, find and run the Edit Configurations action. In the Run/Debug Configurations dialog, click and select JAR Application. Name the new configuration: HelloWorldJar.
Java 11 is still very new.
I suspect IntelliJ's caches got corrupted and clearing them should help.
I would also keep Intellij up to date if using such a new JDK.
