"the dot" connects classes and objects to members. The places where you use it in what I cover are:
(1) when you are connecting an object reference variable to a method. The Extending Existing Classes lesson introduces the dot operator for this use, and
(2) when you are connecting a class name to one of its static fields. An example of this is the dot between "System" and "out" in the statements we use to print stuff to the console window. System is the name of a class included in every Java implementation. It has an object reference variable that points to a PrintStream object for the console. So, "System.out.println( "text") invokes the println() method of the System.out object.
