Java Iterable interface and IteratorJava Iterable interface and Iterator iterator Iterator The interface is defined as follows: public interface Iterator { boolean hasNext(); E next(); void remove();} This interface only contains three functions. The hasNext () and next () methods appear in our common set traversal.Functions:Use next () to obta

The Java Collection class library separates the interfaces and implementations of the set. The same interface can be implemented differently. The basic interface of the Java Collection class is the collection interface. The collection interface must implement the iterator interface. To indicate the interfaces of the Collection framework, java. Lang and

Definition of iterable:Java.lang Bag/** * Implementing this interface allows a object to be the target of * the "foreach" statement. * * @param /** * Returns An iterator over a set of elements of type T. * * @return an Iterator. * /iteratorDefinition of iterator:Java.util Package:Public interface IteratorIterator is an iterator class, and iterable is designed to iterate using foreach as long as the interface is implemented.The itera

1. iterator is an iterator class, and iterable is designed to iterate by using foreach as long as the interface is implemented. 2. the iterator interface is encapsulated in iterable, and iterator iterators can be used as long as the class of the Iterable interface is implemented. 3. Collection collection, List, and set are all implementation classes of

Iterable is an interface which provides Iterator.An implementation of being one Iterable that provides an of Iterator itself: Public Interface

To implement a class that can be used with a foreach loop, you must implement Iterable, which overrides a Iterator method, which returns a iteratorThe code is as follows:public class Itertest implements IterableStores the contents of the array private object[] Obj=new object[1];//record the number of elements added to the private int size;Records the current element's subscript private int current=0;//add element public void Add (String str) {Determ

! =expectedmodcount)Throw Newconcurrentmodificationexception (); } }The idea for the remove operation is broadly consistent except that Lastret is replaced with a list node lastreturned, which is also set to null after each remove. The get element is not obtained directly through get (i), as in the parent version. The iterator saves two adjacent node pointers lastreturned and next. When the element is removed (lastreturned=null), it can still be moved in the linked list because the next point

Total: Java provides a relatively complete set of container classes, the basic types are: List, set, Queue, Map, these object types are called collection classes.one, interface inheritance relationship:Iterable interface, in Java.lang package, Collection, List, Queue, set interface inherit Iterable interfaceAs can be seen, list, Queue, set these three interfaces are in the Java.util package, inherit from th

Parent interface of Collection:iterable interfaceA class that implements the Iterable can is used with the new for-loop.The interface has only one Iterable method:Public interface IterableIt is possible to use your own collection type classes with the new For-loop. To does so, your class must implement the java.lang.Iterable interface. Here is a very basic example:public class MycollectionAnd here is the co
