Enhanced for-loops iterate through every element in the specified array unless the loop is stopped (using break or another control flow modification).

Code:

int[] array = {1, 2, 3};

for(int i : array){
   // current iteration
}

In the above example, the enhanced for-loop can execute only three times since the size of the array is 3. The local variable "i" in the enhanced for-loop scope holds the currently iterated element. The elements are iterated in the order of the array. If the enhanced for-loop is on its 2nd iteration, for example, the "i" local variable is equivalent to "2".

Here is a demonstration.

Code:

for each integer in the array, iterating in order, setting the local variable named "i" to the current iterating index value,{
     do this
}

You can use the enhanced for-loop with any class inheriting from "Iterator"; which is how Java Collections work with them.

I'd delete this for grave-digging, but it's quality.
