Enhanced For loop

o The enhanced for loop eliminates the need to use java.util.Iterator to iterate over a collection.

List<String> list = new ArrayList<String>();

list.add(“One”); list.add(“Two”); list.add(“Three”);

for (String item : list)

{

System.out.println(item);

}

o The enhanced for loop works with any array or collection class that implements the new java.lang.Iterable interface.

o The Iterable interface defines a single method called iterator() that returns a java.util.Iterator object.

o Unlike using Iterator, the enhanced for loop doesn’t allow you to remove items from the list during iteration.
