In this step, I will download the installer from the Oracle website. First, open a web browser and navigate to https://www.oracle.com/java/technologies/javase-jdk16-downloads.html. Select the desired file based on the operating system. For this step, I chose the Windows 64 installer and accepted the license agreement.

In this step, I will verify the installation by checking the java -version command’s output.

java -version

Oracle has not released the JDK 16 docker image yet, but there are other JDK 16 docker image available from DockerHub. In this step, I will get the adoptopenjdk/openjdk16 image and install it in a Docker container.

docker pull adoptopenjdk/openjdk16

C:\MaryZheng\DockerImages>docker pull adoptopenjdk/openjdk16
