Iterator is known to be a behavioral design pattern that allows you to traverse components of a set without revealing the representation underneath (for example: stack, lists, tree, etc.). Assume we are developing an application that needs us to keep track of a collection of alerts.
Iterator Design Pattern
According to GoF definition, an iterator pattern provides a way to access the elements of an aggregate object sequentially without exposing its underlying representation. It is behavioral design pattern. As name implies, iterator helps in traversing the collection of objects in a defined manner which is useful the client applications.

Iterator design pattern hides the actual implementation of traversal through the collection and client programs just use iterator methods. Iterator Pattern Example Let's understand iterator pattern with a simple example.

Iterator Design Pattern explained with simple example SimpleTechTalks
In object-oriented programming, the iterator pattern is a design pattern in which an iterator is used to traverse a container and access the container's elements. The iterator pattern decouples algorithms from containers; in some cases, algorithms are necessarily container-specific and thus cannot be decoupled.
What is the Iterator Design Pattern?
The Iterator pattern lets you do all this. The key idea is to take the responsibility for access and traversal out of the aggregate object and put it into an Iterator object that defines a standard traversal protocol. The Iterator abstraction is fundamental to an emerging technology called "generic programming".

3. Java Iterator Design Pattern - Real Life Example. The best way to understand any design pattern is to map it to a real life example and try to code a solution accordingly. A perfect example of an iterator design patterm is the MP3 player control. The user can't worry about viewing their play list when they see it.
Iterator
Today's pattern is the Iterator pattern which formalizes how we move through a collection of data in a particular class Iterator in the Real World MP3 player control is a good example of an iterator.
Iterator Design Pattern Javagyansite
The iterator pattern is a great pattern for providing navigation without exposing the structure of an object. Traverse a container. In Java and most current programming languages, there's the notion of a collection. List, Maps, Sets are all examples of a collection that we would want to traverse.

The pattern: the iterable and its iteratorยถ. Let's now step behind the for loop and learn about the design pattern that powers it. The traditional Iterator Pattern involves three kinds of object. First, there's a container object.. Second, the container's internal logic lets it corral and organize a number of item objects.. Finally, there's the key to the pattern: instead of the.
Iterator Design Pattern Tutorial with Java Code Example for Beginners Iterator Pattern
Iterator pattern is very commonly used design pattern in Java and .Net programming environment. This pattern is used to get a way to access the elements of a collection object in sequential manner without any need to know its underlying representation. Iterator pattern falls under behavioral pattern category. Implementation

Iterator (Design Pattern) Software Ideas Modeler
The Iterator pattern addresses such recurring problems when dealing with aggregate objects. What this pattern says is that aggregate objects should provide a way to access its elements sequentially without exposing its internal structure.
Iterator
Iterator is a behavioral design pattern that lets you traverse elements of a collection without exposing its underlying representation (list, stack, tree, etc.). Problem Collections are one of the most used data types in programming. Nonetheless, a collection is just a container for a group of objects. Various types of collections.
