2,826 PointsHey there do you have to use Camel Casing on Variables too?
So I am wondering about this question because when the teacher is creating the code he puts a capital N in name in the variable like this:
String firstName = "etc";
how come the variable is put in that way the capital n in name and no capital f in first. What I am really asking does it really matter to do it that way in Java.?

2,826 Pointsahh okay that makes sense. but I'm wondering is it a necessity though in java why not have both lower case? or is it just how the java system works to put it that way.?

13,811 PointsThe aim of these conventions is just to make the code more readable - you can visually separate e.g. a type from an instance immediately by looking at the case which is used. They're not "enforced" in any way by the Java compiler though, if that's what you mean.
