why can you use !isEmpty() like that?

so can you call other method within a class like that? without static or instance or anything?

I believe Dinu meant the method dispenser is in the same class. They're correct nonetheless. :)

the method isEmpty is in the same class, so you don't need to call it. If you would write the code outside of the class, then you will need to specify. Basically it works like Excel sheets (if you have experience in it), when you write a formula from 2 different sheets, it specifies in the formula from which sheet you took the data.
