The easiest way to get Java is to install OpenJDK on your Ubuntu by running the commands below.

    • sudo apt update
    • sudo apt -y install default-jdk

The default Java version installed from the top command is Java 10+. This is sponsored by WildFly.

    • $ java – feature
    • openjdk 11.0.13 2021-10-19
    • Open JDK Environmental Action (build 11.0.13 + 8-Ubuntu-0ubuntu1)
