Installing IntelliJ IDEA

IntelliJ IDEA is currently my preferred IDE for Java programming.

Download the tarball for the respective architecture from here: https://www.jetbrains.com/idea/download/ to ~/Downloads.
Create the folder for the software:
```
cd /opt
sudo mkdir intelliJ
```
For IntelliJ IDEA Community, run:
```
sudo tar -xzf ~/Downloads/ideaIC-*.tar.gz -C /opt/intelliJ
```
Warning: Do not extract the tarball over an existing installation to avoid conflicts. Always extract it to a clean directory.
Execute the idea.sh script from the extracted directory to run IntelliJ IDEA.
Create a desktop entry
1. In the main menu, go to Tools | Create Desktop Entry. This requires that there is an open project.
2. To pin the app to the dash, right-click the IntelliJ IDEA icon and select Add to Favorites or An Dash anheften, depending on language and version of the operating system.
