1.  Once the install wizard is finished, set the `JAVA_HOME` and `PATH` environment variables. 

   Set `JAVA_HOME` to the installation location, noting that the directory contains the currently-installed version. For example, if the default directory is used for 17.0.20, then set `JAVA_HOME` as `C:\Program Files\Amazon Corretto\jdk17.0.20_10`.

   Add `%JAVA_HOME%\bin` to the current `PATH` variable.

1.  Verify the installation by running **java -version** in a command prompt. You should see the following output.
