I will show you 2 visual tips
that will give you feedback when you type expressions.
Let’s imagine that I write C, uppercase, that’s the start
of a class name. It is in italics because it shows that
in the system there are indeed classes beginning with letter C.
So now, if I write Color, we see that there is
one and the system detects one.
If I write Colox, it is red, meaning: “I don’t
have classes beginning with this prefix.
There is the same thing for methods.
If I write nx, it will be red.
“nne” also. However, “ne” shows that “New” exists.
