I'm trying to figure out what this is actually called and where I can find the answer for it. I can't understand the difference in
for (Treet treet : treets) { }
I don't know what the different "treet" mean. can someone help me or at least tell me what it's called?
for (Treet treet : treets) { }
This is an enhanced for statement (although often referred to as an enhanced for loop). You are saying that you want to do something for every element in some collection of things. (Well, actually, you're doing nothing here, but never mind).
In English: "For every Treet in treets, do something".
Treet is a type. Somewhere you need a class called Treet defined. If it's in a different package, you need to import it.
treets is either an Iterable<? extends Treet>, meaning you could call treets.iterator() and use the result in the standard hasNext()/next() way; or an array of something which extends Treet. It's something you can iterate through.
treet is a single element from the iterable/array. You can use it only inside the body of the loop.
Thats a forach loop, it iterates through the array/list/... and performs the actions defined in the loop to every element in the list which is referenced by treet.
