Thread: strange for-loop what is it doing?

hey,

So I'm learning java right now, and I saw something strange in a programming tutorial on Youtube.

this is the normal for loop:

// example
for (int x = 0 : x <= 5 : x ++) {
//code here
}

but then I saw something like this:

for ( String s : getConfig().getConfigurationSection("kits"))
{
// code here
}

only 2 things inside the "()" things (don't know the english word for that ..)
I mean not :

for ( thing 1 : thing 2 : thing 3)

but

for (thing 1 : thing 2)


what does that do ?
I mean is that an infinite loop or what .. I don't understand that ..

thanks for help

BTW The clause separators in the first example should be ; not :

Not just an array, but any Collection or array.

Not just an array or Collection, but any class, even a class that is not a collection, that implements the Iterable interface can be iterated via a foreach loop.
