An error in his code which ain't showing up..

SO I found this probable error in his code which is not showing up..

He used the method "isEmpty" in the method "dispense" before he declared it.

Shouldn't this give an error as java reads the code from the top to bottom? WHy isn't an error showing up?

Not sure if you still need help clarifying this, but here goes. I don't think it matters the order the methods are created in because when you create a new instance of the object in the main method it will gain access to all of them.

i got it. The answer is that java is a compiled language and the compiler reads the code more than once so it can connect all the methods with their calls. I was getting confused as I thought that java worked like an interpreted language and was not familiar with the idea of compiled languages

I think I know what you're referring too, he created the method in the The PezDispenser class so he didn't have to declare it in the Example java file.

noo im not talking about "Example java file.". I am talking about the PezDispenser class file.In the PezDispenser class file he used the isEmpty helper method in the method dispense before he declared it. Won't that give an error. Shouldn't you use something AFTER you have declared it?
