"this" lets you refer to a runtime object during design time. For
example, let's say we have a method in Student that lets them sign up
for a course. When they sign up, we want to pass a reference to that
Student object to the course. How do we refer to "that" student, since
there may be many individual Student objects? That's what "this" gives
you:
public class Student{
public void signup(Course aCourse){
aCourse.enroll(this);
}
}
Then, we have...
Student joe = new Student();
joe.signup(new Course('Java for ColdFusion Programmers'));
So, in that case, "this" refers to joe.

Yeah, Ray corrected me on that one.

It isn't? What is it then? I mean, I know that it's a way reference
attributes/methods inside the object, but what is it technically
referred to
as? Just curious.
