Java Collection Framework

Collection frame work provides architecture to store and manipulate collection of objects. Collection of object behaves like an object. We can perform all operation like sorting, searching, and deletion on group of objects by using collection framework.

The Java Collections API’s provide a set of classes and interfaces to handle collections of objects.
By using these classes and interfaces we can handle these objects easily. We can understand collection in different way also its behaves like a array whose size changed dynamically.

Rather than having to write your own collection classes, Java provides these ready-to-use collection classes for you.

Most of the Java collections are located in the java.util package. Core Java Training in Jaipur  also has a set of concurrent collections in the java.util.concurrent package.

Hierarchy of collection framework. Java.util package contain all the classes and interface for collection framework.

Iterator and ListIterator in Java

Iterator and ListIterator are interfaces provided by Java API that are used to iterate over a Collection. They are both part of the Java Collection Framework. ListIterator is a sub-interface of Iterator and is specifically used to iterate of a List.
How to use an iterator? Each of the collection implementation provides an implementation of an iterator that can be used to iterate over it. Below example show how to obtain an iterator from a collection object and use it to iterate over the collection.

Each collection object provide an iterator() method that can be used to obtain the iterator object. The hasNext() and next() method can be used to traverse over the elements of the collection as shown in the example below: publicclassTestClass{publicstaticvoid main(String[] args){Set<String>set=newHashSet<String>();set.add("One");set.add("Two");set.add("Three");Iterator<String> iter =set.iterator();while(iter.hasNext()){System.out.println(…

Java Coaching Centre in Jaipur

Core Java Training in Jaipurprograms are so designed to help a student with little or no knowledge of any programming language get comfortable and be able to develop cool applications using this powerful programming language.
Java programming language is originally developed by James Gosling at Sun Microsystems and released in 1995 as a core component of Sun Microsystems' Java platform. The language derives much of its syntax from C and C++ but has a simpler object model and fewer low-level facilities. Java applications are typically compiled to byte code (class file) that can run on any Java Virtual Machine (JVM) regardless of computer architecture. This programming language is a general-purpose concurrent class based object oriented programming language, specifically designed to have as few implementation dependencies as possible. It is intended to let application developers "write once, run anywhere". Introduction to JavaWhy java is better for Internet?Features of Java…

Summer training for Computer Science Student

It is without any doubt that the computer is the most vital device. Whether it is with regard to education or a workplace, the computer comes in handy in every regard. The primary reason for this is the fact that it can handle many tasks at hand, and much faster for that matter. With this said, it would be easier to understand the sudden increase in Summer Internships for computer science students.
It is for this reason that the demand for trained professionals in computer sciences is going up day by day. The students who pursue this course manage to do very well once they have picked up the strategy and tools needed for the trade. But no amount of education is going to be handy unless the person, who is undertaking it, knows how it is to actually work in the field. This is one of the reasons why a lot of attention nowadays is being paid to such a form of education. This may take part in the following ways: 1)The students are sent to take part in internships in the prominent companies i…

Internship for Computer Engineeres

Are you passionate about technology? Do you like solving problems? Do you have a deep ambition to create something new and change the world? If you answered yes to these questions, computer engineering is the career path for you. This article is all about this branch of engineering and its scope. So, keep reading!
Unlike its hardware counterpart (Electronics and Communication Engineering), computer engineering focuses completely on software. Throughout their four years of university education, students of this field learn about the general design, creation, and maintenance of system as well as application software. With a deep focus on software algorithms and coding, this branch of engineering is certainly challenging and fun if you have a deep interest in, and passion for, computers.
Why study computer engineering?
This field can indeed be a very fruitful one for those who know their way around it. Here are some reasons why:
1. Financial Security:
There are records of comp…
