Note:
Installing a JDK update release replaces the existing version of the same feature release. For example, when you install JDK 27.0.1 after installing JDK 27, the installer uninstalls JDK 27 and installs JDK 27.0.1. However, you can install JDK 27 and JDK 11 simultaneously. In the JDK installation location,jdk-27 and jdk-11 directories get created.
