∟Install and Manage Java Packages on CentOS

This section provides a tutorial example on how to install OpenJDK 11 JRE (Java Runtime Environment) on CentOS 8 systems using 'dnf/yum' as the package manager.

If you want to run Java applications on CentOS Linux systems, you can follow what I did on my CentOS 8 computer:

1. Login as "herong", who has admin privileges.

2. Run "dnf search" to find available Java packages. I see OpenJDK 1.8 and OpenJDK 11 packages available for installation:

herong$ dnf search java

java-11-openjdk.x86_64 : OpenJDK Runtime Environment 11
java-11-openjdk-src.x86_64 : OpenJDK Source Bundle 11
java-11-openjdk-demo.x86_64 : OpenJDK Demos 11
java-11-openjdk-devel.x86_64 : OpenJDK Development Environment 11
java-11-openjdk-jmods.x86_64 : JMods for OpenJDK 11
java-1.8.0-openjdk.x86_64 : OpenJDK Runtime Environment 8
java-1.8.0-openjdk-src.x86_64 : OpenJDK Source Bundle 8
java-1.8.0-openjdk-demo.x86_64 : OpenJDK Demos 8
java-1.8.0-openjdk-devel.x86_64 : OpenJDK Development Environment 8
java-1.8.0-openjdk-javadoc.noarch : OpenJDK 8 API documentation
java-1.8.0-openjdk-headless.x86_64 : OpenJDK Headless Runtime Environment 8
...

3. Install the OpenJDK 11 JRE (Java Runtime Environment):

herong$ sudo dnf install java-11-openjdk

Dependencies resolved.
