for (Iterator<String> i = someIterable.iterator(); i.hasNext();) {
String item = i.next();
System.out.println(item);
}
Note that if you need to use i.remove(); in your loop, or access the actual iterator in some way, you cannot use the for ( : ) idiom, since the actual iterator is merely inferred.
As was noted by Denis Bueno, this code works for any object that implements the Iterable interface.
If the right-hand side of the for (:) idiom is an array rather than an Iterable object, the internal code uses an int index counter and checks against array.length instead. See the Java Language Specification.
for (int i = 0; i < someArray.length; i++) {
String item = someArray[i];
System.out.println(item);
}

Java For-Each Loop
The for-each loop is simpler and more readable than a regular for loop, since you don't need a counter (like i < array.length). The following example prints all elements in the cars array:

The construct for each is also valid for arrays. e.g.
String[] fruits = new String[] { "Orange", "Apple", "Pear", "Strawberry" };
for (String fruit : fruits) {
// fruit is an element of the `fruits` array.
}
which is essentially equivalent of
for (int i = 0; i < fruits.length; i++) {
String fruit = fruits[i];
// fruit is an element of the `fruits` array.
}
So, overall summary:
[nsayer] The following is the longer form of what is happening:
for(Iterator<String> i = someList.iterator(); i.hasNext(); ) { String item = i.next(); System.out.println(item); }Note that if you need to use i.remove(); in your loop, or access the actual iterator in some way, you cannot use the for( : ) idiom, since the actual Iterator is merely inferred.

It's implied by nsayer's answer, but it's worth noting that the OP's for(..) syntax will work when "someList" is anything that implements java.lang.Iterable -- it doesn't have to be a list, or some collection from java.util. Even your own types, therefore, can be used with this syntax.

1 week ago - In order to fix it, you have to add a variable in the scope of the outer loop to hold the suit: // Fixed, though a bit ugly for (Iterator i = suits.iterator(); i.hasNext(); ) { Suit suit = (Suit) i.next(); for (Iterator j = ranks.iterator(); j.hasNext(); ) sortedDeck.add(new Card(suit, j.next())); } So what does all this have to do with the for-each construct?

January 20, 2026 - The foreach statement enumerates the elements of a collection and executes its body for each element of the collection. The do statement conditionally executes its body one or more times. The while statement conditionally executes its body zero or more times. At any point within the body of an iteration statement, you can exit the loop by using the break statement.
