Java Loops Types For Each - ashish9342/FreeCodeCamp GitHub Wiki
Also called the enhanced for loop, it is an extremely useful and simple way to iterate over each item in a collection, arrays as well as objects that implement the Iterable interface.
for (object : iterable)
{
// Statements
}
The loop is read as - for each element in the iterable
(could be an array, collectable etc.). The object
type must match the element type of the iterable
.
int[] number_list = {0, 1, 2, 3, 4, 5, 6, 7, 8, 9};
for (int numbers : number_list)
{
System.out.print (numbers + " ");
//Iterated 10 times, numbers 0,1,2...9
}
Output:
0 1 2 3 4 5 6 7 8 9

In the above code snippet, number_list
is an array. If you don't know what this is, don't worry about it. An array is a container object that holds a fixed number of values of a single type, but more on this later.
