I wasn't sure to post here or in the StackOverflow community but here goes...
I have Ubuntu 18.04.3 LTS installed on my laptop. I'm trying to set up IntelliJ at the moment. I installed my jdk by running
apt-get install default-jdk which installed java in my /usr/bin/java directory. However, when coding, I am unable to see the source library code in IntelliJ. I only see the decompiled .class files, which isn't really easy to read, and doesn't contain any comments.
Basically, my question boils down to: How do I download the openjdk 11.0.3 source code and make intelliJ use that?
