INTRODUCTION Java is an object-oriented programming language developed by James Gosling and colleagues at Sun Microsystems in the early 1990s. Unlike conventional languages which are generally designed to be compiled to native code, Java is compiled to a bytecode which is then run (generally using JIT compilation) by a Java virtual machine. The language itself borrows much syntax from C and C++ but has a much simpler object model and does away with low level tools like programmer-manipulable
Literature Review on Java Development Berzal (2005) investigated on the tools and frameworks that are available for Java application development. This was to explore the merits and demerits of tools and frameworks. This researcher made good review of various frameworks in Java platform. The frameworks include Struts, Tapestry, WebWork, InternetBeans Express, Velocity and Cocoon. The purpose of these frameworks is to help developers build web applications systematically. They all support the design
Input controls are used to ensure that the data entered into a system is correctly, completely, and is secure. The input controls can help the flow of data in a database to be the same format and easy to understand. There are many times of input controls, however the paper goes into detail about four types of input control which are: input mask, validation rules, source documents, and batch input. Without input controls there can be data integrity errors that could occur and cause information to
Java is a programming language and one of the most popular languages used today. Like all other programming languages, there are reasons for the development of a new one. Two basic reasons for the development of a new language are to adapt to the always changing environment, and to create improvements for programming. Java was created for a couple of different reasons that also stay true to the basic reasons for development and this essay will highlight those reasons. This essay will also going over
Function Block Diagram The Function Block Diagram (FBD) is a graphical language in PLC which describes the function between the input output variables. FBD is in the form of elementary blocks and number of blocks are connected together to form a logic using connection lines or links. A function block is represented in the manner shown as: The connection is oriented, i.e. the line carries data from left to the right end. The connected blocks must be of the same data type (like integer, double integer
Object Oriented Programming - OOP Overview of Object Oriented Programming Object Oriented Programming is type of programming in which programmers define not only the data type of a data structure, but also the types of operations that can be applied to the data structure. The data structure becomes an object that includes both data and functions. In addition, programmers can create relationships between one object and another. Object-Oriented programming (OOP) entered the software development;
classes rather than just one so it is less directly accessible by the computer system. Unlike procedural programming which uses an algorithm, object oriented programming is made simpler to code. Examples of a object oriented language would be C++, Java and Microsoft Visual Basic. Object oriented programming is a language model organised around objects rather than actions and data rather than logic. Object Oriented is a specific class that has two areas, state and behaviour. It not only describes
Java is one of many high-level programming languages that use abstraction (reducing and factoring details) to create software for computers and many other electronic devices. Compared to low-level programming languages, high-level programming languages use a mixture of natural language (any language used by humans) and typical computer terms to create an easier to understand and simpler form of programming. Figures 1 and 2 show the difference in writing a simple program called “Hello World” in
three centuries, batik has become one of the best means of expression, spiritually and culturally, in the values of Southeast Asia. This means of coloring and decorating textiles has even reached a higher degree of excellence in the island of Java. From Java, batik cloth has been exported to many other islands, spreading the batiking art around, which is how it is so well known, as are most of the items used to create it. A number of different materials are used when creating a batik. The primary
I have been programming in C/C++ for six years, including bachelor degree tenure. During the academic years, the degree curriculum covered many courses which involved C/C++ programming such as Introduction to Programming in C, Data Structures, Object Orient Programming, System Programming, Computer Graphics, etc. Some of these courses included C/C++ projects as an essential part of the course. In Data Structures, our team of two students had developed Airline Management System in C. In the project
abstract model of a computer. It is the part of a computer that relates to programming (basically machine language). The instruction set supply’s commands to the processor, to tell it what it needs to do. An understanding of an ISA is called an implementation. An instruction set permits multiple implementations that may differ in performance, physical size, and expense etc. because the ISA serves as the interface between software and hardware. An ISA defines everything a machine language programmer
"inheritance", and "polymorphism" that empowers the object to be flexible for reuse whereas PP is not as flexible due to its dedication to an itemized task. (ATK Solutions, Inc., 2015, para 5) Two examples of OOP in today’s programming world are Java and Ruby. (Rouse, 2008) Java is intended for use in dispersed applications on business networks and on the Internet. (Rouse, 2008) Ruby is intended for use broadly in Web applications. (Rouse, 2008) Both the OOP and PP programming language models are designed for
A trouble ticket system is a software system which works on multi-channel customer requests centralised management. It can help streamline work flow processes, track and solve requests more effectively and improve customer satisfaction. Ticket is this case is as same as medical report which records trouble description, process and result. Finally, it is archived after it closeshttp://doc.otrs.org/3.3/en/html/introduction.html. Open-source Ticket Request System (OTRS), is a free, open-source and
PART A 1. Explain class stereotypes; include the boundary class, entity class and control class. BOUNDARY CLASS DEFINISION A "Boundary Class" is a class that lies on the periphery of a system, but within it. It interacts with actors outside the system as well as objects of all three kinds of analysis classes within system. Boundary classes are used to model the interaction between a system and its surroundings, i.e., its actors. The following aspects of the interaction are captured on boundary
The class stereotypes are specially used to identify classes in analysis and early design. Apart from giving process to finding the classes, class stereotypes any affect only a specific area because this stereotyping results in a robust object model. The first class stereotype is boundary class. The boundary class used to model interaction between the system's surroundings and its inner workings. The boundary class interaction is involves transforming, translating events and noting changes in the
The Language of Java What is Java? Java, in it’s simplest definition, is a dynamic computer application that can run a program to accomplish a task. Java runs in all sorts of things in the average person’s life; things such as car stereo systems, televisions, cell phone applications, websites, and more. But, where did it come from, and how does it work, and how has it impacted our lives today? Java was first created by Patrick Naughton, Mike Sheridan, and James Gosling in 1994. However, they started
Abstract—High Performance Computing (HPC) provides support to run advanced application programs efficiently. Java adaptation in HPC has become an apparent choice for new endeavors, because of its significant characteristics. These include object-oriented, platform independent, portable, secure, built-in networking, multithreading, and an extensive set of Application Programming Interfaces (APIs). Consequently multi-core systems and multi-core programming tools are becoming popular. However, today
Java thread is an independent path of execution through programming code. If we execute multiple threads, one thread's path will differ from the rest. For instance, consider an ordinary thread executes the byte code according to if-else statement's if part, meanwhile another thread executes the byte code according to an else part. Here there is a question occuring how JVM (Java Virtual Machine) keeps track of every thread execution. The JVM gives the method called stack to each thread. In order
refers to the ability of a program to be understood by the target user. The fundamental elements in readability are the language syntax and how it is related to the problem domain of the programming language. For example, in general purpose languages as Java or C where target users are mainly developers or engineers, the syntax is close to logical and machine instructions. In contrast, in the design of Domain Specific Programming Languages (DSL) the reduction of the required amount of programming expertise
Recently, the agile methods become the most widely used software development methodologies. Most agile methods try to minimize risk by developing software in short time boxes, called iterations. While agile methods are in a wide spread use but there are few research trying to mine or visualize the degree of agility between the agile methods. In this paper, formal concept analysis (FCA) is used as data mining tool to visualize the degree of agility in six agile methods, by building formal concepts
