Trouble Understanding Java code of a URCap

I am trying to learn how to develop a URCap with UR’s Starter Package. I have a some knowledge on Java, but very little on APIs. I have watched all the UR tutorials on developing URCaps (https://plus.universal-robots.com/myfirsturcap/1-using-the-starter-package/), but I am still struggling to make my own custom URCap. Could anybody lead me to some resources that would further explain how to use Java or API’s for URCap devlopment?
