Java 5.0

This interface defines a single method for returning a java.util.Iterator object. Iterable was added in Java 5.0 to support the for/in loop, which is also new in Java 5.0. The Collection, List, Set, and Queue collection interfaces of java.util extend this interface, making all collections other than maps Iterable. You can implement this interface in your own classes if you want to allow them to be iterated with the for/in loop.

The type variable T specifies the type parameter of the returned Iterator object, which, in turn, specifies the element type of the collection being iterated over.

public interface Iterable<T> {
// Public Instance Methods
     java.util.Iterator<T> iterator( );
