I can't find JavaFX jar files on after running apt-get install. I don't even think they got installed

I'm trying to build a JFX app on IntelliJ. I installed JavaFX using the command:

sudo apt-get install openjfx

I found somewhere that I am supposed to add jfxswt.jar and jfxrt.jar to the class path. I ran the find command on the root directory but I didn't find either file.

EDIT:
apt policy openjfx output:

openjfx: Installed: 11.0.2+1-1~18.04.2 Candidate: 11.0.2+1-1~18.04.2 Version table: *** 11.0.2+1-1~18.04.2 500 500 bionic-updates/universe amd64 Packages 500 bionic-security/universe amd64 Packages 100 /var/lib/dpkg/status 8u161-b12-1ubuntu2 500 500 bionic/universe amd64 Packages

Edit 2:
dpkg -L openjfx output:

I'm not sure how but it finally installed. Here's the link to the answer that I found:

Openjfx is not installing

The answer is the one by laurenmurphyx64. Here are the commands that I used:

apt purge openjfx
apt install openjfx=8u161-b12-1ubuntu2 libopenjfx-jni=8u161-b12-1ubuntu2 libopenjfx-java=8u161-b12-1ubuntu2
apt-mark hold openjfx libopenjfx-jni libopenjfx-java
