What is a Java collection framework?

 

 

Hi Nimrod,

Java collections framework is a set of classes and interfaces in order to provide a unified architecture for representing and manipulating collections :

Frameworks Aims to : 

Have a high-efficiency. Many of the fundamental collections such as dynamic arrays, linked lists and trees are highly efficient.

Different types of collections should work with a high degree of Interoperability

Adoption and extension of a collections have to be easy.

 

A Java collections frameworks contain:

a. Interfaces.

b. Classes.

c. Algorithms.

 

Java framework defines several Interfaces and Classes. 

Most important Framework  Collection Interfaces are:

1. The Collection Interface

2. The SortedSet

3. The Set

4. The Map

5. The Map.Entry

6. The Enumeration

8. The List Interface

 

Most important Framework  Collection Interfaces are:

1. AbstractCollection

​2. AbstractList

3. AbstractSeuentialList

​4. LinkedList

5. ArrayList

6. AbstractSet

​7. HashSet

8. LinkedHashSet

9. TreeSet

 

Classes and Interfaces of the Collections are located in Java.Util 

Cheers,

Frazier

What is a Java collection framework?

 

This are a set of classes and interfaces

The framework consists of

1- Iinterface which are abstract data types that represent collections

2- Implementations i.e. classes which are re-usable data structures

3- Algorithms which are methods that perform several computations such as searching &sorting objects that implement collection interfaces

It gives a program access to data that has been pre-packaged and algorithm for manipulating the data

What is a Java collection framework?

Java collections framework set of classes and interfaces that implement commonly reusable collection data structures.

 

Collection framework goals:

 

     >>high-performance

     >>allow different types of collections to work  

     >>Extends an element (a key/value pair) in a maping a collection to be easy.

 

Collection framework interfaces :

 

        > Collection Interface

        > List Interface 

        > Set

        > The Sorted Set 

        >   Map

        > The Map.Entry

       > The Sorted Map 

       > The Enumeration
