5 INTERESTING FACTS ABOUT JAVA

Java is simple and robust general purpose programming language. It supports multiple platforms and has some in-built security features as well. Here some interesting features about Java that may surprise you, are discussed:

1) Unique features of Java:

Undoubtedly, Java comes with many unique features. Java is Object oriented programming language. Its platform independence and neutral structure helped in the growth of the language. Java is simple yet very safe and secure to use. This is evident from the trust that the developers are showing towards the programming language. Programs built on Java will work effectively on both desktop and mobile devices. The language is strong, robust and supports multiple threads. Other unique features of Java include its dynamic performance and portability.

2) Identifiers in Java:

Identifier is the term that refers to all the program components like variables, class, methods and objects. These form the four basic components of Java programming. Objects include behaviors of the states. For example, a car has states like model and colorwhereas behavior includes speed and mileage. Class serves as a blue print that describes the states and behavior of the objects. Syntax of the Java is incomplete if any of the four components are absent from the code.

3) Case Sensitiveness of Java:

A point to note is that Java is a case sensitive language. So, the interpretation of the identifiers (variables, class, methods and objects) depends on the case used. Thus the upper and lower case of the identifiers should be treated as differently and has to be taken care of in coding. Therefore, “welcome” and “Welcome” would have different meaning in Java programming. A letter (K or k), $ sign and underscore can be used at the beginning of the identifier. Never think of using keyword as an identifier.

4) Mascot of Java:

'The Duke' is the Java Mascot. It was made by Joe Palrang. Palrang is the person who has dealt with the Hollywood blockbuster, Shrek. Duke is commended at Oracle. A living, life-estimate Duke is a prevalent element at each gathering of Java developers. Every year, Oracle comes up with another Duke identity. A world famous celebrity is made the mascot of Java on each year.

5) Attractive User Interface (UI) and User Experience (UX):

Java offers the most popular UI. At present, more than 5 billion cell phones are working in Java. Also 275 million TV sets and Blu-Ray players are supported by Java. This language is ceaselessly positioned first in the rankings by the programming designers as the best decision in their programming career. Java platform provides a very soothing user experience owing to its attractive and eye-catching user interface.

Interesting Hidden Facts Between Selenium /QTP

Both QTP and Selenium were developed with the objective to provide functional and regression test automation for various software and web applications.Selenium and QTP are platforms or frameworks composed of sophisticated tools and apparatus to help in automation of the web browsers. Both of them have their own advantages and disadvantages. It is the experience and discretion of the tester or engineer that will help him choose the best for the optimization of results for a particular application.Learn to Selenium Training @http://www.metaforumtechnologies.com/selenium-training-in-chennai

Given below is the detailed contrast and analysis of QTP and Selenium based on a number of parameters:

1) Origin:

QTP stands for Quick Test Professional. It was initially developed by Mercury Interactive (MI). In 2006, MI was subsequently acquired by Hewlett Packard (HP). Nowadays, it is popularly known as HPE Unified Functional Testing (UFT) software. Selenium was developed by an engineer and programmer of Thought Works, named Jason Huggins in Chicago in 2004. The invention of Selenium was made accidently as a Java Script Test Runner. It was then updated in the following years to cater to the ever increasing demands of the Information Technology and Industry.

2) Cost of Licensing:

The major difference between Selenium and Quick Test Professional or Unified Functional Testing framework is the starting and working costs. Selenium being open source platform is completely free to use. This means that there’s no licensing or renewal cost associated with the Selenium tool. On the contrary, QTP is not open source testing tool. It is a commercial tool and is expensive. User needs to buy an initial license and renew it periodically if QTP platform is chosen for test automation. So, the cost of HPE UFT is huge as compared to Selenium framework that is free of cost.

3) Types of automation testing supported:

If you are just thinking about the huge cost of QTP, please consider the support that the platform provides for various types of test automation. HP QTP or UFT can be used to test both client and server side applications like built in TCL/TK and PowerBuilder. It supports testing of both desktop and web based applications. On the other hand, if you are planning to go for Selenium, remember that you will be able to automate only the web based applications. Selenium is portable but one needs to spend in lakhs for obtaining valid QTP license.

4) Scalability and Programming Support:

Quick Test Professional tool supports only Visual Basic (VB) scripts and Java scripts. But Selenium has good scalability and scripts can be developed in any of the programming languages like Java, C#, Ruby, Python, PHP, Perl, .Net and Groovy etc.Therefore, more object oriented language support is available for open source Selenium test tool as compared to only two OOL for QTP. In other words, one can say that the QTP tool is less scalable. Object Oriented Approach of automation testing becomes more challenging in QTP owing to its less mature programming language i.e. Visual Basics. Unlike QTP framework, Selenium is based on much more mature language like Java.

5) Platform or Operating System Support:

Selenium has support for almost all the platforms like Windows PC, MAC, UNIX and LINUX. As far as Quick Test Professional is concerned it has support for only Windows operating system or platform.
