That for loop is called a 'for-each loop'

It is is a shorthand notation for writting a loop that acts over an 'iterable collection'

That is to say the object (numbers in this case) need to implement the Iterable interface http://docs.oracle.com/javase/7/docs/api...rable.html

Which just means that it provides a standard interface to looping over all the objects in the collection(array). Basically it provides a nice object that has methods next() hasNext() and remove() for you to loop over. Look at the Iterator interface for more information: http://docs.oracle.com/javase/7/docs/api...rator.html

So you're code behind the scenes would be translated to something like the following:

Code:

Iterator<Int> ite = numbers.iterator(); while(ite.hasNext()) { int item = ite.next(); System.out.println("Count is: " + item); }

@chmod you're thinking too functionally. for (int item : numbers) might look like a functional construct but its a shorthand notation.
