- Iterable Interface. The Iterable interface is the root interface for all the collection classes. The Collection interface extends the Iterable interface and therefore all the subclasses of Collection interface also implement the Iterable interface.
- Collection Interface. The Collection interface is the interface which is implemented by all the classes in the collection framework. It declares the methods that every collection will have.
- List Interface. List interface is the child interface of Collection interface. It inhibits a list type data structure in which we can store the ordered collection of objects.
- ArrayList. The ArrayList class implements the List interface. It uses a dynamic array to store the duplicate element of different data types. The ArrayList class maintains the insertion order and is non-synchronized.

A framework is a set of classes and interfaces which provide a ready-made architecture. In order to implement a new feature or a class, there is no need to define a framework. However, an optimal object-oriented design always includes a framework with a collection of classes such that all the classes perform the same kind of task. To get more about...
The utility package, (java.util) contains all the classes and interfaces that are required by the collection framework. The collection framework contains an interface named an iterable interface which provides the iterator to iterate through all the collections. This interface is extended by the main collection interface which acts as a root for th...
This interface contains various methods which can be directly used by all the collections which implement this interface. They are:
The collection framework contains multiple interfaces where every interface is used to store a specific type of data. The following are the interfaces present in the framework.
Learn about the Java Collection Framework, a set of classes and interfaces that provide a consistent and efficient way to group objects. Explore the hierarchy, methods, and examples of various collections such as List, Set, Map, and more.

- Interfaces of Collections FrameWork. The Java collections framework provides various interfaces. These interfaces include several methods to perform different operations on collections.
- Java Collection Interface. The Collection interface is the root interface of the collections framework hierarchy. Java does not provide direct implementations of the Collection interface but provides implementations of its subinterfaces like List, Set, and Queue.
- Subinterfaces of the Collection Interface. As mentioned earlier, the Collection interface includes subinterfaces that are implemented by Java classes. All the methods of the Collection interface are also present in its subinterfaces.
- Java Map Interface. In Java, the Map interface allows elements to be stored in key/value pairs. Keys are unique names that can be used to access a particular element in a map.
- Introduction. The Java platform includes a collections framework. A collectionis an object that represents a group of objects (such as the classic Vectorclass).
- Collection Interfaces. The collection interfaces are divided into two groups. The most basic interface, java.util.Collection, has the following descendants
- Collection Implementations. Classes that implement the collection interfaces typically have names in the form of . The general purpose implementations are summarized in the following table
- Concurrent Collections. Applications that use collections from more than one thread must be carefully programmed. In general, this is known as concurrent programming.
- Why Collections Framework? The collections framework was designed to meet several goals, such as − The framework had to be high-performance. The implementations for the fundamental collections (dynamic arrays, linked lists, trees, and hashtables) were to be highly efficient.
- Java Collections Framework. A collections framework is a unified architecture for representing and manipulating collections. All collections frameworks contain the following −
- Hierarchy of Collection Framework. All classes and interfaces for the collection framework are available in java.utli package. The following diagram shows the hierarchy of the collection framework in Java
- Java Collection Interfaces. The collections framework defines several interfaces. This section provides an overview of each interface − Sr.No. Interface & Description.
