1. Find your Java installation directory. Assuming that you didn't change the path for the JDK or JRE during installation is not changed, it should be in a directory under C:\Program Files\Java. There are a few ways to find the full path: Open File Explorer, click This PC in the left panel, then navigate to C:\Program Files\Java. The directory you're looking for should have the name of the JDK version, such as C:\Program Files\Java\jdk-19. If you installed the JRE instead of the JDK, you'll have something like C:\Program Files\Java\jre1.8.0_351 instead. You can also open the command prompt ... 2. Open your Advanced System Settings. Here's how: Press the Windows key on your keyboard and type advanced system. Click View advanced system settings in the search results. 3. Click the Environment Variables button. You'll see it at the bottom-right corner of the System Properties window.
