Can you explain in more detail what exactly you don't understand?

Do you understand the for-loop in line 23? Do you know what the different kinds of collections are and how they work (HashSet, ArrayList, TreeSet, LinkedList)?

Those first four lines are calls to the method named addRange, where the method is called with two arguments: a collection of Integer objects and an int.

See Defining Methods and Passing Information to a Method or a Constructor in Oracle's Java Tutorials.
