It follows the conventions of Apache Maven for its directory structure and includes two sample applications that print "Hello World!" to standard output: * a Java console application with a command-line interface, and * a Java Swing application with a graphical user interface.

Snaps are applications packaged with all their dependencies to run on all popular Linux distributions from a single build. They update automatically and roll back gracefully. Snaps are discoverable and installable from the [Snap Store](https://snapcraft.io/store), an app store with an audience of millions. ### Enable snapd Snap is available for [Red Hat Enterprise Linux (RHEL) 8](https://www.redhat.com/en/enterprise-linux-8) and RHEL 7, from the 7.6 release onward. The packages for RHEL 7, RHEL 8, and RHEL 9 are in each distribution’s respective [Extra Packages for Enterprise Linux](https://fedoraproject.org/wiki/EPEL) (EPEL) repository. The instructions for adding this repository diverge slightly between RHEL 7, RHEL 8 and RHEL 9, which is why they’re listed separately below. The EPEL repository can be added to **RHEL 9** with the following command: ``` sudo dnf install https://dl.fedoraproject.org/pub/epel/epel-release-latest-9.noarch.rpm sudo dnf upgrade ``` The EPEL repository can be added to **RHEL 8** with the following command: ``` sudo dnf install https://dl.fedoraproject.org/pub/epel/epel-release-latest-8.noarch.rpm sudo dnf upgrade ``` The EPEL repository can be added to **RHEL 7** with the following command: ``` sudo rpm -ivh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm ``` Adding the *optional* and *extras* repositories is also recommended: ``` sudo subscription-manager repos --enable "rhel-*-optional-rpms" --enable "rhel-*-extras-rpms" sudo yum update ``` Snap can now be installed as follows: ``` sudo yum install snapd ``` Once installed, the *systemd* unit that manages the main snap communication socket needs to be enabled: ``` sudo systemctl enable --now snapd.socket ``` To enable *classic* snap support, enter the following to create a symbolic link between `/var/lib/snapd/snap` and `/snap`: ``` sudo ln -s /var/lib/snapd/snap /snap ``` Either log out and back in again or restart your system to ensure snap’s paths are updated correctly. ### Install Hello Java!
