Comparison between AngularJS 1 and Angular 2 in the Implementation of the Presentation Layer of Multitiered Ecommerce Applications

This paper focuses on application built using the Java Platform, Enterprise Edition (Java EE). In this application, the business-tier is based on representational state transfer (RESTful) web services, and the presentation tier adopts Angular(x) framework.

Java Functions Scenarios To Generate JUnit Classes

Unit testing is a practical approach for increasing the correctness and quality of software; but writing unit test code is exhausting and tedious job; and requires a great deal of time and effort. So even with the use of frameworks for writing and running unit test such as JUnit this will need a great deal of time and effort. As a consequence, there is a pressure in writing testing code. So we present in this paper a new method to generate unit testing automatically in order to speed up the testing process and reduce the cost. We have implemented this method on the Java programming language, where we write a new specification called JFS describes the behavior of the function in terms of input and output. This specification is written inside the code class and is independent of the code, and it can be written before starting the code phase and thus achieve the principle TDD Test-Driven Development which is based on written test-first in order to improve the development process. After writing specification we will generate test classes for the execution of unit testing (we used JUnit as framework to execute unit testing) based on the new specification.

Development of an Object Oriented Library based on Java 3D to Facilitate the Construction of Virtual Environments in Driving Simulators

A driving simulator is a combination of hardware and software that enables the user to navigate through a real-time computer-generated virtual driving environment. Driving simulators are very valuable for conducting driving studies that are infeasible or unethical to conduct on the road. For studies that can be conducted in the real world, driving simulators provide a more cost effective solution and allow a much higher degree of flexibility in terms of changing the conditions of the environment for experimental purposes. The corner stone when conducting any study on the driving simulator is the construction of a virtual driving environment that serves the purposes of this study. Even though driving environments can considerably vary between different studies, they all share the presence of common components that exist throughout the environment like roads, traffic signs and other components. The objective of this paper is to present the design of an object-oriented library that facilitates the construction of virtual driving environments when conducting studies on a driving simulator. The proposed library uses object orientation to hide implementation details from the designer of the environment which results in making the construction of such environments easier and more productive as well as their modification later if needed. The proposed library is based on the Java programming language and on Java 3D technology which makes it portable and usable on any platform that has an implementation of these two technologies.
