For Each Loop Java

A for loop that is written differently so that it loops through each element in a data structure, as opposed to having a loop counter variable that goes from 0 to length-1.

Say you have an ArrayList<string> called list. You can loop through each element in the list with a for each loop like so:

for(String elem: list)
{
    // use elem here in the body
    System.out.println(elem);
}

As opposed to the traditional for loop:

for(int i = 0; i < list.size(); i++)
{
String elem = list.get(i);
System.out.println(elem);
}
