how do i replace openjdk 17 with 21

I'm assuming you mean you want to replace Java on your local machine because Boatcam is already on 21.

If you haven't installed JDK 21 and ran the installer, you should start by doing that:
https://www.oracle.com/java/technologies/downloads/#java21

If you have but jdk 21 isn't selected, you need to make sure the JAVA_HOME environment variable is set to the path where you installed jdk 21.
