QuoteIf you downloaded the installer from AdoptOpenJDK site, you can skip this step, as the installer adds the Java path itself.
Follow it only if you downloaded OpenJDK / Oracle / archive version as it requires manual edits.
You must add Java path to the system environments when using JDK 11. Java 8 automatically adds it to the path, so for free sources skip this part.
Right click on your Computer > Properties > Advanced system settings > Environment variables, select the Path variable and click Edit button > and then set the path to your JDK installation.
