You can install using the toolbox command. The Toolbox is a tool that offers a familiar RPM based environment for developing and debugging software that runs fully unprivileged using Podman. I recommend reading the toolbox command documentation using the command toolbox --help or github.com/debarshiray/toolbox/tree/master/doc
Create a new toolbox container using the command:
toolbox create --release f33
To run the toolbox use the command:
toolbox enter --release f33
To install OpenJDK use the command:
sudo dnf install java-11-openjdk
